A lunatic finds other crazy people to go on adventures with. The fate of the islands they visit is solely decided by whoever feeds the Captain first.

It’s a cartoon about a boy who is very stretchy because he ate a magic fruit who is determined to become the king of all pirates. To do that he has to have fistfights with other people who ate magic fruits which gave them different powers. Everyone shouts out the name of their special moves during the fights. There is a lot of shouting in general.
