		"Be good to your dough." - Dr. Bones Cookie

Cookies, being the most prominent species in Earthbread, have become the main driving force in its history. They are nearly indistinguishable from humans aside from their simplified makeup and appearance. Cookies were initially baked by the Witches as a dessert, but they have started being given sentience and other purposes by their makers thanks to the Life Powder that's mixed into their dough. This art of baking has been passed to some Cookies and they have used it to bake their own offspring.

However, many Cookies have been born through other means and with varying shapes, which has made the Cookie species, as a whole, more diverse.

Anatomy

Cookie bodies are flat, but still wide enough to contain a skeleton and blood. No matter the flavour of each Cookie, their dough will always contain Strawberry Jam, which serves as their blood. It is unclear what Cookie bones are made out of, but it's most likely they consist of hardened sugar or calcium. The inner workings of their bodies are quite mysterious as the Life Powder mixed in them does all of the work, not necessarily requiring anatomy such as organ systems.

Cookie facial features tend to be made out of icing, such as their eyecing, mouth, and facial hair (if they have some). Cookies have noses but they are not too visible. It is likely that Cookies breathe through their pores. The same can be said for their ears^[2] that they claim to have^[3]. The ingredients that make up their hair tend to vary for each Cookie- in general they tend to have hair that matches their main ingredient, but many Cookies can be seen to have hair made out of cream and icing. Even so, the type of cream used can vary based on each Cookie's main ingredient.

Their limbs tend to have a mitten-like shape but the length and width of each limb differs per Cookie. Cookie hands seem to have fingers that they rarely show, as they do not require it to hold their items. A Cookie's dough is lightly coated with sugar that makes them look smooth and shiny, as long as it's properly taken care of^[4]. This coating helps protect them from minor injuries, but is not thick enough to protect their dough from prolonged exposure to liquids. As a Cookie grows up, their exterior becomes tougher and crunchier, though certain ingredients in their dough can also factor in the toughness of their body.

Biology

Cookies and liquids

Similar to humans, Cookies secrete sweat and other liquids from their bodies, but they vary for each Cookie depending on their ingredients- although they typically contain some sugar^[5]. All the activities they do will eventually make their dough dirty, which means they need to take baths. However, Cookies get soggy when dipping themselves in liquid, and therefore every liquid that will be used for baths has to be specially treated before use, or Cookies need to coat themselves with a special oil ready to coat themselves with. This rule doesn't apply to aquatic or sea-faring Cookies who are baked to survive in the seas, and therefore will never get soggy- related to this, the composition and ingredients of a non-aquatic Cookie's dough can also effect their ability to become soggy^[6].

Cookies also can't just dip themselves in any liquid they see, as their sweats might cause unwanted reaction to the liquids^[7]. While they can just use treated water for showers, other liquids can provide extra benefits to their bodies compared to just using water. Every Cookie has different needs depending on what they're made of.

Some parts of Earthbread have been known to produce hot springs that are safe for Cookies even without any treatment done to it, or without the use of any coating before soaking themselves in. One example of such a place is the Latte Hot Springs in Dessert Paradise.

Temperatures

A suitable amount of heat can give Cookies a healthier and crispier dough, as wells as also help release stress. Excessive heat can result in negative effects, such as dizziness. Excessive heat akin to a regular oven has the potential to kill them, which is how Witch bake Cookies to be eaten. While Cookies that are baked for food aren't sentient, those who were baked with Life Powder are unfortunately subjected to feel the blazing heat of the oven.

Cookies who were baked with spicy ingredients, such as peppers, can naturally endure heat better than other Cookies. This endurance can also be built by living near any spicy or hot environments^[8] such as the Dragon's Valley, or by keeping the body tough and crunchy. This rule applies to cold temperatures as well. Naturally, younger Cookies have lower tolerance to extreme temperatures as they have softer exteriors.

Consumables

Jellies are the staple food for all Cookies. Excluding the bear jellies, the shape of jellybeans can vary according to its flavours, sometimes following the shape of the original food flavours they mimic. While Cookies tend to love sweets more compared to other food, they do need variety in their diet to keep it balanced by adding vegetables and savory food to their diet. Even as a living dessert, Cookies still need to pay attention to their sugar levels.

Most Cookies tend to have the food, or drinks they were baked with as their favorite item to consume. A notable example of this is Cocoa Cookie who appears to love her cocoa drinks excessively. However, this trait will quickly become unhealthy when left unsuppressed.

Reproduction Methods

Baked by Witches

Witches play a big part in Earthbread's history, as some of the first witches that managed to harness the essence of Life that flows through natural systems, allowing them to create sentient Cookies.

Baked by Wizards

Wizards tend to bake Cookies according to their needs, and instead of imbuing the dough with Life Powder, they harnessed Moonlight. Cookies are made with a purpose in mind and are immediately put to that purpose upon birth- being trained by their assigned Wizard, before being put to work helping them.

Parent Cookie

It is known that some Cookies bake Cookies of their own without the influence of Witches or Wizards, although exactly how and when are details largely unexplained. One theorem posits that singular Cookies can create offspring by contributing pieces of their own dough:

Nonetheless, it is unclear whether this method is something truly done or simply a tall tale. What is clear is that Cookies are able to produce offspring through one way or another, as exemplified by the many parent-child relationships throughout the series.

But whether it was done or not, this excerpt implies that Cookies reproduce asexually, and don't require a second parent figure to make their offspring. However, Cookies, being a social species similar to their human creators, do pursue romance with one another, and might want to start a family together. While most Cookies shown to have familial bond are only shown with one parent, some do have 2 parental figures, such as Langue de Chat Cookie. The method remains the same, except the dough might contain 2 sets of Cookie DNA/crumbs, with each crumb coming from one parent.

No, they do not get pregnant, they're too flat for that- their bodies would crack if they do. But of course, if you insist, you can always visit the beautiful and exciting world of fan fiction. Take note that doing so will be at your own risk, and Cookie Run Wiki accepts no liability for any psychological trauma incurred.

Non-Baking methods

Lab-made Cookie

Cookies that are born in a cold lab instead of a hot oven. They tend to be the result of experiments done by either Witches or fellow Cookies. Notable examples of this method of "baking" are Lemon Cookie and Ion Cookie Robot.

Imbued by nature

Sometimes Life finds its way to create things on its own (or with the Sugar Swan's help). They don't necessarily need a batch of dough to make their bodies/vessel, as they can infuse themselves with elements of nature and create a Cookie body out of them, however they're not fully opposed to infuse themselves with an already available dough laying around. Notable examples of this method are Wind Archer Cookie and Cookiemals.

Life Cycle

Birth

Most Cookies start their life journey from an Oven, as a batch of dough. The one thing that makes these sentient Cookies different from your regular Cookie is the presence of Life Powder imbued in their dough, which new batches can procure through various methods preferred by their creator. Just like how humans normally bake desserts, Cookies can be born alone or in a group, as a batch of dough can be used to bake multiple Cookies at once. A notable example of this is GingerBrave and GingerBright who are born from the same batch. However, being batchmates doesn't automatically correlate to a familial relation or bond batchmates, unless it was specified by their baker. For example, GingerBright herself was baked with the intention of giving GingerBrave a friend, and is sometimes even treated as his love interest.

Upon birth, some Cookies are given purpose for their existence by their creators- mostly to work for them. As not all Cookies start their life from infancy, they are instilled with a certain mental age that defines how old they act/behave, and they master basic life skills such as walking and speaking. For example, GingerBrave who was freshly-baked as a child/preteen was immediately able to speak, walk, and run away from his creator.

Lifespan

Cookies age through an extremely prolonged process of freshness and staleness: young Cookies are considered to be fresh and soft, while older Cookies have grown stale and hard. Those of good health and spry bodies are referred to as “crispy.”

It can be assumed that mortal Cookies can live for roughly the same amount of time as humans. However, some Cookies don't start their life from infancy and it is unclear whether these Cookies born as infants and Cookies born not as infants have different age scales. Those who aren't baked as infants are instilled with a certain mental age upon birth that defines their age, and will behave accordingly.

Like humans, Cookie ages affect the maturity and capabilities of Cookies and how they are treated in society. There are distinct splits between different age brackets just as there are with humans: Cookies can be considered infants, children, young adults, older adults, and elderly all the same based on how old they are and the mental age with which they were born. Younger Cookies often attend school and are cared for by older Cookies, older Cookies fill work archetypes, and elderly Cookies may end up retiring.

Some outside sources can prolong or halt a Cookie’s aging process indefinitely, though this effect tends to apply to only very special, powerful individuals. Examples include Legendary Cookies whose duties are too important to allow them to die, and the Dragon Cookies whose arcane power allows them to live for eons as a species. These Cookies, too, tend to have a mental age that almost always presented as mature adults.

Death and the Afterlife

The word "Crumbling" or "Crumble" has become synonymous with Death due to the nature of Cookies' brittle bodies that break easily when injured, although Cookies don't always die this way. Age progression comes with its own issues such as mobility-related problems,^[9] which increase the likelihood of a Cookie’s body failing them.

Cookies can be killed in various ways. Their leading cause of death has historically been consumption by witches, but as presence has decreased significantly, and this timeline of Cookie Run is one that's set in a peaceful time without war, most Cookies now die of natural causes. Other deaths that has been shown in-game includes ones caused by magic (petrification^[10], etc), murder^[11], extinction^[12], natural disasters^[13], accidents^[14], torture^[15], and suicide^[16] (allegedly).

However, for a society with rampant use of magic, death does not necessarily mark the end for these sentient Cookies. It is possible for Cookies to be revived or reborn when they have the means. A famous example of this is Fire Spirit Cookie who was reborn by the Red Dragon's powers.

Cookie souls can linger around the mortal plane if they haven't felt at peace with their deaths. Notable examples of these include Onion Cookie who isn't even aware of her death, and White Ghost Cookie who felt the need to protect her old school from being demolished. Notably, other Cookies often don't seem to notice that these Cookies have passed away, mistaking them for living.

The concept of afterlife for Cookies is quite unclear, so far only Angel Cookie has spoken about Heaven, or an equivalent of it. Meanwhile, the word “Hell” has become synonymous with the Oven, and unlike Angel Cookie, Devil Cookie has never spoken about anything related to the Cookie equivalent of Hell or the underworld- although their CookieRun: Kingdom bio explicitly mentions "the fiery lower trays of existence", heavily implying there is also a Cookie equivalent to Hell. Angel Cookie's Trial seems to take place in a heaven-like location, and is named "Celestial Temple at Dawn", while Devil Cookie's takes place in a hellish location, aptly named "River of Hellfire".

Varieties

Cookies come in a variety of shapes and forms depending on how they were baked, and their given purpose. These will be split into 2 categories, humanoid and non-humanoid.

Humanoid Cookies

---

These Cookies have a humanoid body that fit perfectly with the typical shape of a cookie cutter, no matter how and what they are made of.

Regular Cookies

Cookies that are not listed in other categories are considered to be regular, ordinary Cookies. These Cookies were baked with organic ingredients that are typically used to bake Cookies (ie; flour, sugar, butter, etc.), and born with the typical Cookie body shape with no extra body features- just enough for their daily activities. Any extra ability they have either comes from their source ingredient, their occupations, tricks and other things they've learned in their lifetime, or modifications they made to their body.

While they were all baked with organic ingredients, not all of them are made with edible ingredients as some of them have been mixed with non-food or poisonous ingredients. Some examples of this are Candlelight Cookie who was baked with candle wax, and Poison Mushroom Cookie who was baked with poisonous mushroom.

This is the most common type of Cookie in Earthbread. They live ordinary lives, and die in an ordinary ways.

Nova Cookies

These Cookies were born out of a supernova that occurred to a colossal star candy years ago. These Cookies emerged together as the 4 fragments of the star scattered, eventually becoming sugar-substitute planets. Nova Cookies are destined to embody the values pursued by each of their planets and emerge as their leader.

While each Nova does have differences in biology, they do share some similarities. They consider each other family as they were born from the same star. As their names suggest, none of them contain actual sugar, and instead were baked with alternative sweeteners. So far, Universe Ablaze has revealed Xylitol, Stevia, Allulose, and Aspartame as their sugar substitutes, and each sweeteners have their own characteristics. Each Novas inherited the power of the stars, said power manifesting differently for each of them.

Being a race of Cookies that are born outside Earthbread, all of these Cookies have gotten accustomed to the different condition in outer space, and therefore does not require oxygen to breathe. Compared to other alien lifeforms, Nova Cookies are able to withstand the extreme conditions of space better, but they are not completely immune to them. Appearance wise, they look identical to regular Cookies, with some differences that can be seen on their faces and eyes. Their pupils resemble the orbital shape of a star system, and they have facial markings that stretch from their eyes to the edges of their face.

Non-Organic Cookies

Cookies that are not made with typical organic ingredients you can find in other Cookies, but still identify themselves as Cookies. They can come in a variety of shapes, depending on their purpose. Some examples of these Cookies are: Ion Cookie Robot, who was mass-produced by Aloe Cookie to mimic actual Cookie behavior through its built-in AI, Cyborg Cookie, who's body was also made by Aloe Cookie to help them recover from an accident, and Lollipop Cookie who was first made to just be a lifeless cookie-shaped doll, until she gained sentience after Butterbear Cookie fixed her.

Undead Cookies

Undead Cookies can be divided into 2 groups, pure Cookie Ghosts, and dough-bound Undead Cookies.

Cookie ghosts seems to anchor themselves to the mortal world when they feel like they still have unfinished business,^[17] and therefore didn't die peacefully. They are normally invisible to the naked eye, but can reveal themselves to anyone the ghost wants to see. They might be able to control which living desserts get to see them, but are always visible to other ghosts/spirits. A notable trait of these Cookie ghosts is the lack of moisture in them, because they- quite literally- do not have a body. Cookie ghosts can switch between their old appearance and their new ghastly form, however their ghastly form will become dominant by time, as less and less Cookies remembers them^[18]. They can also grow in size depending on how much fear they absorbed from their target Cookie.^[19] Notably, Cookie ghost's that retaining their Cookie form can easily be mistaken for regular living Cookies.

Dough-bound undead Cookies are Cookies baked with odd materials, or through odd circumstances, usually revolving around life and death. Some were baked through revival, some were baked with odd ingredients such as actual zombie cells^[20] found in graves, and as usual, Life Powder will make do with whatever ingredients they were fused with and make it work. Not much is known about how these Cookies work as they vary case by case, and they are almost never documented either.

Non-Humanoid Cookies

---

These Cookies either barely fit the typical cookie cutter shape or do not fit it at all. The design of their bodies either have hints of inspirations from the original animal they're based on, or are baked with said animal in their dough. These extra animal features end up sticking out to some degree, which makes their body not fit for the typical cookie cutter design.

Hybrids

A fusion of Cookies and animals. The range of this type of Cookies can span from the more humanoid-looking Cookies that retain some animal features, to Cookies that look more like an animal rather than a regular Cookie, such as Cookiemals. This type of Cookies can exist anywhere, but they prominently reside in the Dessert Paradise or underwater in the sea. These Cookies commonly have extra abilities thanks to their animal features, which can range from heightened sense of smell, flight, or the ability to breathe underwater. Cookies that live underwater have been specifically baked to never get soggy. Other abilities not listed in here will differ based on the animal features each Cookie have.

Cookies in this list will be ordered based on the range of appearance specified above, with the first ones only having their extra features serve as decorational purpose.

Hybrid Cookies
Principal Pave Choco	Millennial Tree Cookie	Dark Enchantress Cookie	Matcha Cookie
Centipede Cookie	Strawberry Cream Cookie	Sugar Glass Cookie	Amber Sugar Cookie
Gold Honey Cake Cookie	Blue Slushy Cookie	Red Panna Cotta Cookie	Scorpion Cookie
Abyss Monarch Cookie	Electric Eel Cookie	Cookiecutter Shark Cookie	Fig Cookie
Goblin Cookie	Lobster Cookie	Mocha Ray Cookie	Anglerfish Cookie
Jelly Serpent Cookie	Choco Cup Cookie	Squid Ink Cookie	Pond Dino Cookie
Cookiemals		Choco Flounder Cookie

Shapeshifters

A step further from the Hybrid Cookies. In addition to having animal features, they can also transform into said animal, or into a Cookie form they've adopted. The ability to transform is achieved through either magic or other means that have yet to be known. Additionally, some Cookies or creatures are also born with this ability. The range for these Cookies can span from those who were originally born a Cookie and gained the ability to transform into other species, to those who sought a Cookie form to achieve something they can't do in their original species' form or innately have the ability to change between forms.

Cookies (and their alternative forms) in this list will be ordered based on the range specified above.

Shapeshifter Cookies
Werewolf Cookie Werewolf	Moon Rabbit Cookie Rice Cake Rabbit
Snake Fruit Cookie Serpent	Crowberry Cookie Crow
Sugar Swan Cookie Sugar Swan	Cream Unicorn Cookie Cream Unicorn
Sorbet Shark Cookie Sorbet Shark	Kumiho Cookie Marshmallow Fox
Longan Shaman Cookie Longan Chocolate Cream Wyvern	Longan Lancer Cookie Longan Earl Grey Cream Wyvern
Black Sugar Swan Cookie Black Sugar Duck	Cream Ferret Cookie Cream Ferret

Dragon Cookies

They are not real Cookies, but merely just another form of a bigger species, the Dragons. The Earthbread as a whole has been losing energy, which has led the Dragons to take on a Cookie form to conserve their own energy. They can revert back to their original Dragon form whenever they have ample power left. Some notable features of these Dragon Cookies are their slit pupils in their eyes, their gems, and their ability to fly.

Dragon Cookies (and their real Dragon forms) in this list will be ordered based on their release dates.

Dragon Cookies
Pitaya Dragon Cookie	Ananas Dragon Cookie
Lychee Dragon Cookie	Lotus Dragon Cookie
Longan Dragon Cookie

Trivia

• Cookies typically name themselves after the main ingredient they're made out of, but some have changed their names to be based on their occupation or their titles.
  • Most famous example of this is Croissant Cookie's alter ego who changed her name to Timekeeper Cookie.^[21]
• Devsister's Notion site mentioned that Cookies have no need for bones and organs, however they still end up forming a set of skeleton in their dough anyway.^[22]
• Just like how eating a Cookie's own ingredient isn't considered cannibalistic, eating Strawberry Jam is not considered that either.^[23]
• So far, only GingerBrave has a confirmed fixed height, standing at 15cm tall^[24]. Give or take, other Cookies presumably or presumably not have about the same height.
  • Through the Into the Catch! Teenieping World story, Heartsping mentioned that GingerBrave is around the same size as her and other Teeniepings.^[25]
  • GingerBrave has been used as a scale of measurement for the Dragon Cookies and their Dragon forms^[26].
    • In order from smallest to largest, Lychee Dragon Cookie is 0.7 GingerBraves (GB) tall, Lotus Dragon Cookie and Pitaya Dragon Cookie are 1.3 GB tall, Ananas Dragon Cookie and Longan Dragon Cookie are 1.4 GB tall, Lychee Dragon is 3 GB, Ananas Dragon is 5 GB, Lotus Dragon 5.5 GB, Pitaya Dragon 8.5 GB, Longan Dragon 16 GB, and Longan Dragon's Colossal Dragon form is 5,438,967.8 GB.
• Ancient Cookies do exist in Cookie Run: OvenBreak^[27], but they don't seem to be equipped with a Soul Jam, as none of them are alive at the moment. Whether White Lily Cookie is alive as Dark Enchantress Cookie or not remains unknown as the game never touched that subject.
