Quick recap
The third film, non-canon. Geysers fling the crew onto an island of strange animals looking for a new king. One of Chopper's cries is mistaken for the royal call, and he's crowned. Young Mobanby, whose naturalist father was killed by pirates, asks him to stay. The villain is Count Butler, who controls beasts with his violin and is after the animal king's horns. He hypnotizes Luffy for a while, eats the horns and turns into a giant monster. The Straw Hats beat him, the island's steam forms a crown over Mobanby, the real new king, and Chopper says a tearful goodbye.
