Tarumanma

The Tarumanma-gō (タルマンマ号) was an anime-only ship used by Tony Tony Chopper and Roronoa Zoro in the Donut Race. Chopper provided power for the ship by peddling on it. But it was destroyed by the Foxy Pirates who wanted revenge for the destruction of the Kaji King.

"Taru" means barrel. "Manma" means plain or bare.
