One Piece Odyssee

Zunesha is a gargantuan elephant, comparable to an island in sheer scale; its two-jointed legs are disproportionately and extremely long, such that it can walk on the sea floor while its upper body, including about a third of each leg, remains above the water. However, Zunesha has comparatively small eyes sunken deep into their sockets, being barely visible at most times and giving the impression that it has no eyes at all. Its gray skin is heavily wrinkled, reflecting its old age, and its ears are tattered and frayed at the edges

Most of Zunesha's personality is a mystery, but it does not mind carrying a civilization on its back, and in fact cares greatly about the Mink Tribe

Zunesha was born a thousand years ago in the New World. At one-point, Zunesha became a companion of Joy Boy. 800 years ago, Zunesha committed a crime and was sentenced to walk the seas for eternity and only act upon being ordered to do so. Since then, it had wandered the sea of the New World and lived for centuries carrying the Mink Tribe and the other lifeforms on Zou.
