Pipì, Pupù and Rosemary realize that, in order to find Mapà, they’ll have to cross the Ocean and go to the other part of the world, and so they organize a trip on a ship which is commandeered by three pirate rats, a.k.a. the ‘Pirats.’ Once they are aboard the ship, the trio discover that the Pirats’ intention is not to transport them but to devour them during the voyage and so they try to escape from the ship until an albatross comes and saves them and finally carries them off to an island on the other side of the ocean.
