Marron (ちびくりちゃん, Chibikuri-chan) is a Ham-Ham who appeared in Hamtaro: Rainbow Rescue and some of the Japanese episodes. She likes nuts and is friends with Tomy-T and Eggy-P. She also seems to have a friendship with Penelope.
Notes
Marron is often called Chestnut, because her Japanese name literally means "small chestnut", but since she was called Marron in Rainbow Rescue (video game), that is her official English name.
