Carrot from the anime One Piece. She is part of an animal race called Minks and is a Rabbit Mink. She is very friendly, and very strong and fierce fighter. The Straw Hats meet her and the other Minks on a living island kingdom called Zou. After they helped out her people from the aftermath of a devastating attack, she sneaks on Luffy's ship and joins Luffy, Nami, Chopper, Brook and fellow Mink, Pedro (A leopard Mink), off to rescue Sanji and bring back this Poneglyph rubbing. She, obviously, love carrots and never take her carrots without permission or feel her wraith, as Luffy nearly got defeated cause he ate her carrot. Like all Minks, she can use an ability called Electro, a electricity charge attack.
