Stella is a humanoid penguin female, with a chubby and curvaceous body. She leads the Fishbone Cult, a quasi-religious group entirely centered around fish. Stella has a fish obsession, which bleeds into every aspect of her excitable and hyperactive personality, to the point that the Fishbone Cult's common accepted food is fish-shaped cookies. Stella completely takes off her clothes when she's excited, which is almost always.
