World 3-Castle (New Super Mario Bros. Wii)

World 3-Castle is the Castle level of World 3 in New Super Mario Bros. Wii. This is the first level to feature Bob-ombs.

Layout
The level star with some ice cubes, several Dry Bones and ? Blocks, which one of them contain a Penguin Suit. To progress, Mario must enter a Warp Pipe. Mario will find a Ice Snake Block which he must use to avoid the Bottomless Pit and reach the end of the castle. Falling icicles will fall in the Ice Snake Block, and Mario will find spikes and three circus balls. The Ice Snake Block will lead Mario to a Warp Pipe. After entering the Warp Pipe, Mario will find two Pipes which spawns Bob-Ombs, Bob-Ombs frozen in ice cubes, and another Ice Snake Block. The Ice Snake Block will lead Mario to the door leading to the battle with Lemmy Koopa. Before the door, there's a Warp Pipe which Mario can access to obtain a Penguin Suit using circus balls to bounce onto the ? Block. When Mario enters in the door, he will find Lemmy Koopa again. Kamek turns Lemmy's circus balls bigger so it will be harder for Mario and co. to hurt Lemmy. As he takes damage, Lemmy's circus balls will grow bigger in size after he is done sliding his shell to attack Mario and gang.

Star Coins
