Cocoa

Cocoa is a light brown bunny with a brown heart-shaped nose and brown cheeks, along with eyelashes under her eyes and a darker brown chocolate droplet between them. Her ears are long, floppy, and dark inside, tied together with what appears to be a white elastic band. She has a white tail and white fluff around her neck, made of whipped cream.

Her character is kind and cheerful, she always tries to help other Tunas, even if they don’t ask for it.
Persistence - She believes that even the "evilest" Thuns need help sometimes, and sometimes forces her help on others before giving up.
Optimism - Cacao believes that everyone, even unfriendly tunas, deserves help.
Naivety - for example, in dialogues with Bessie, Cocoa still considers her her friend, probably unaware of Bessie's discontent and envy towards her.
