Cake

Cake the cat is the gender-swapped version of Jake the dog, created by Adventure Time character designer Natasha Allegri and featured in the episode "Adventure Time with Fionna & Cake". She can stretch, bend, and morph her body like Jake. Cake travels with Fionna, who is the female version of Finn. Lord Monochromicorn is Cake's boyfriend, just like Lady Rainicorn is Jake's girlfriend. As a cat, she also possesses the ability to see in the dark, while Jake has a keen sense of smell. It is also shown that when ever danger is around, the fur on her tail stands on end or "frizzes out". She is scared of Marshall Lee who is the male version of Marceline.

Appearance
Strangely enough, she doesn't look much like Jake, aside from their body proportions. She has white eyes in which the pupils become circular if surprised, excited, shocked, or scared. Her eyes are the inverted verison of Jake's). She has a cat muzzle and a small nose (compared to Jake's), cat ears, white fur with many coffee colored spots, and a large bushy tail.
