How do you get the little pirate ship in super smash bros brawl

To unlock the Pirate Ship stage, you must unlock the playable Toon Link character, either by playing through the Subspace Emissary and subsequently entering the secret door in one of the worlds or by fighting upwards of four hundred brawls in multiplayer. Once this is achieved, a battle with Toon Link will be triggered, and once he is defeated you will unlock both Toon Link and the Pirate Ship.
