ONE PIECE: Chopper's Kingdom on the Island of Strange Animals

While sailing, the Straw Hat Pirates find a map to Crown Island, an island inhabited by strange animals. They hear rumors of a "golden legend" on Crown Island and decide to investigate. A sudden accident separates Chopper from his crewmates. Just as the animals on the island are searching for a new Animal King following the death of the old one, Chopper appears and is mistakenly worshipped as the new Animal King... Nami finds the map to Crown Island, prompting the Straw Hat Pirates to go treasure hunting. Unexpectedly, Chopper gets separated from the group and is mistaken by the island's animals for a messenger sent by the gods. He inexplicably becomes the Animal King and befriends Mobambi, the only human boy on the island. When Luffy and the others come ashore to look for Chopper, they encounter Count Batler and his henchmen, who are also after the king's treasure. To protect the island's animals, the timid Chopper steps forward, leading to a fierce battle. What exactly is the king's treasure? Can Luffy and his crew escape safely?
