Mint colored dragons are the most peaceful of all dragons; they only eat plants unless they scavenge meat from an already dead animal. They also have no ways to attack others or defend themselves. They are much smaller than other forms of dragons since they only double in size when they mature. Mint dragons are unable to use magic and cannot fly since they lack wings. Their looks have given rise to the common insult of calling dragons “large lizards.”

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Cake The Cat is the best friend and constant companion of the Speckle-Throated Dragon Fionna The Human. This feisty Mint is determined not to let her diminutive size and lack of wings stop her from having a good time, so she simply hitches a ride on Fionna's back as the two dragons explore forests and caves, wandering far and wide in their quest for adventure. Unusually, Fionna and Cake live together in a treehouse, away from the main Cave. Although she has never taken a mate, it is rumoured by some that Cake has a crush on Lord Monochromacorn, the Horse Dragon companion of Fionna's friend Prince Gumball Of Ooo.
