One Piece, Vol. 14: Instinct
Join Monkey D. Luffy and his swashbuckling crew in their search for the ultimate treasure, One Piece! As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally gained the power to stretch like rubber...at the cost of never being able to swim again! Years later, Luffy sets off in search of the One Piece, said to be the greatest treasure in the world... Someone has given Dorry the Giant exploding ale and he's not happy! Assuming it was Luffy and crew, he launches an all-out attack and is soundly defeated by the rubbery power of the Gum-Gum Rocket! But mystery is afoot--if Luffy didn't slip the giant the exploding brew, just who did?
