Nanimonai Island

In the anime Nanimonai Island is an uninhabited island just beyond Arabasta. Miss All-Sunday gave Luffy an Eternal Pose to this island to help the Straw Hats reach Arabasta, but Luffy destroyed the pose, refusing to let her choose their route. As confirmed during the Little Garden arc, this island is actually feces left by a giant goldfish, one of Usopp's lies becoming true. "Nanimonai" means "Nothing" in Japanese.
