3 Lemmy's Castle

Lemmy's Castle is the third castle occupied by a Koopaling in Super Mario World. It is guarded by Lemmy Koopa. The first part of the hallway contains some Magikoopas who cast spells at the Mario bros.. If these spells hit one of the many Turn Blocks in the castle, that block will be transformed into an enemy. A checkpoint can be reached if the player hits the P-Switch and reaches the closest door before the time limit is up. The second part of this castle is another long hallway, this time, consisting of blocks that move up and down in a set amount of time. In order to reach the other side the Player must move carefully in order not to get crushed by the blocks and also be wary of the Dry Bones that may be around.

Boss Battle
Lemmy Koopa, one of the Koopalings, is the third boss of Super Mario World. He jumps out of one of the pipes in the room, along with two fake Lemmys, while a Podoboo bounces around the room. Mario must identify the real Lemmy and stomp on him three times to defeat him. Mario will then proceed to the next area, the Twin Bridges.
