#7 Larry's Castle
#7 Larry's Castle is a level in Super Mario World. It can be accessed through either the completion of the level Valley of Bowser 4, or through the secret exit of Valley Ghost House. This level starts with a moving Raft that goes all throughout the first room. In the first room, the player will encounter Ball 'n' Chains and spikes. When the raft reaches the top of the level with a door on the right, the player may choose to take the door, or to stay on the raft. If the player stays on the raft, he will see a midpoint section, two Dragon Coins and a Super Mushroom. The door on the right of that section will lead to the same room as the door above. In the second room, the player will see Dry Bones, Magikoopas and a few Fireballs, or Podoboos. The yellow blocks are walls, and the player either needs to swing them with a Cape Feather, or allow the Magikoopa to break them. If the Magikoopa breaks a yellow block, it will turn into a Yellow Koopa Troopa, a Thwimp, or a 1-Up Mushroom. Before the final red door, there is a Green ! Block, which gives the player a Cape Feather.
The player fights Larry Koopa at the end. The fighting method is similar to that of Iggy Koopa in Iggy's Castle, except there will be three Podoboos that rise up and go down. When this level is cleared, the player will gain access to Front Door.
