The LevelEdit

The level has a splitpath at the beginning. The lower path leads you to a dead end with 2 power-up boxes while the other path goes straight to the next room. In order to defeat this level, just head for the goal using the koopa shell from the second room of the level or beat the secret exit.

Secret ExitEdit

Do everything in the normal exit up to going through the blue pipe with the shell, but when you throw it, follow it to the right so that it bounces on hitting the brick block and deactivates an ON/OFF block. Go back through the pipe and to the left, then through the door to fight the Big Boo Boss.

Big Boo BossEdit

The Big Boo Boss is a rare kind Boo that is identic to Big Boo that appears in this level, in which Mario or Luigi must throw the P-Switch, the key, and the Koopa's shell at Big Boo to defeat him. to defeat it. As soon as one of the objects hits it, the Big Boo disappears moves to another part of the room, and reappears. When you beat him, you typically unlocked the secret exit. The Big Boo Boss, as any other Boo, is immaterial, and as such, can go through walls and floors. Unlike Big Boo and little brother, Big Boo Boss cannot harm the player.
