Bonnie

Bonnie (affectionately referred to as Bonnie-chan) is a pet boar owned by Ganju Shiba. Bonnie is tattooed with kanji lettering on it's side which roughly translates to "four-wheeled drive". At one point it is implied that Bonnie was accidentally cooked into a stew by Retsu Unohana during a friendly cookout including her, Ganju, and a few others from the 4th Division. However, Bonnie is shown alive and well later.
