Layout
Yoshi starts the level on the titular ship filled with enemies, and must enter a Warp Pipe to appear in a Para-Koopa-infested area. Here, the player must locate a door which enables them to go inside an area with some enemies and a vase. Yoshi must break the vase to reveal a key and find another door which transports him to a Middle Ring and a pipe. It leads him back outside, where he must enter another pipe into a room with Tap-Taps and find a door leading to a room with Pirate Guys. Yoshi needs to locate a door and enter a room with Potted Ghosts where he must find another key and head back outside. The player needs to unlock a door leading them to a room with some Boos, and find a door there. This door takes the player to a Middle Ring, a Stork Stop, and a boss door which leads to Bessie Bass. The player can defeat her by hitting her when she leaps out of the water. Yoshi can then access the next level.
