Bonnie

Bonnie (affectionately referred to as Bonnie-chan) is a pet boar owned by Ganju Shiba.

History
She was found by Ganju's brother Kaien in a mountainous area of Rukongai, when she was a piglet. She was injured at the time and was looked after by Kaien. Bonnie's ribbon was given to her by Kaien. Bonnie was very fond of Kaien and she is still not as emotionally attached to Ganju as she was to his brother.

Appearance
Bonnie is a reddish-brown boar with an angry expression. She wears a red ribbon which Kaien Shiba gave her on the back. Bonnie is tattooed with kanji lettering on its side, which roughly translates to "four-wheeled drive."

Soul Society arc
She is first seen when Ganju is thrown inside the Elder's house. Uryū, Ichigo, and Orihime are surprised to see a "wild pig" run in. At nine o'clock, Ganju calls her and she jumps above Ichigo, ramming Ganju. Ganju then makes an escape, riding her.
