Sunken Ghost Ship

The Sunken Ghost Ship is in Super Mario World that serves as a gate to the Valley of Bowser. After defeating Wendy O. Koopa, Mario has to swim through this ship in order to make the doorway to World 7 come out of the sea. On board the ship are some Bullet Bills, Mines, Koopas, and a massive swarm of Disappearing Boo Buddies.

Overview
Mario (or Luigi) comes out of a Warp Pipe underwater next to the sunken ship. There is a ? Block nearby, with Bill Blasters nearby. The player must then go down another Warp Pipe that leads under the deck, where Eeries and the massive swarm of Disappearing Boo Buddies can be found. After passing these, there are Circling Boo Buddies and two Boo Buddies. Then there is another Warp Pipe that leads to a huge drop. When the player starts falling, there is a Starman that can be grabbed. On the way down there are Dragon Coins, falling Koopa Troopas and Koopa Paratroopas. There is a platform halfway down with a ? Block that contains another Starman. Farther down there are huge bunches of coins and falling Mines. The player must fall to the right to avoid falling into the water with the Mines. There is a platform on the right with the Green ? Ball that must be touched to beat the level. After Mario beats the level, a giant cave entrance that looks like Bowser's head will rise up out of the water. Mario will enter the cave that leads to the Valley of Bowser.
