World 1-Tower (New Super Mario Bros. Wii)

World 1- is the fourth level in New Super Mario Bros. Wii. This is the first tower level in the game. Larry Koopa is the boss of this stage.

Layout
At the beginning of the level there is a rising brown platform which brings Mario up and lets him hit a ? Block which releases an Ice Flower. The flower will change Mario into Ice Mario allowing him to throw snowballs. There is also a Dry Bones in this area. In the next area there is another rising brown platform for Mario to stand on which will lift him to the first of many swinging platforms. The swinging platforms go back and forth allowing Mario to jump off of one of the two sides. Mario must use this one to jump on to another platform which has two extending brown blocks from the wall which create a staircase for a few moments that Mario must jump up. The next area has another swinging platform with two different ways for Mario to go. The first is the easy way with two platforms and a Dry Bones at the top and the second is the hard way with an extending platform and a Star Coin (Plus multiple regular Coins). In the next area there are three platforms in a line that Mario has to jump up with Dry Bones coming on from the sides. There is once again a fork which forces Mario to either tale the easy way which has several moving platforms creating another staircase or the hard one with multiple immobile platforms for Mario to jump up. At the top of this area is the Bowser Flag.

The next area has a multitude of brown platforms going in and out of the walls creating a staircase for a few seconds before they come together and crush Mario if he is in between them. There is a block with multiple Power-Ups (Propeller Mushroom, Starman, 1-Up Mushroom and Mushroom) followed by another swinging platform leading to a fork. Once again the easy path takes Mario to another (dual) swinging platform and the hard one takes him to a prize; in this case a 1-Up Mushroom. If he takes the easy path and is Small Mario then he can slip through a hole and get the final star coin. The next area is a combination of five swinging platforms with the Red Ring and the Red Coins. To get to the top, and to the door that leads to Larry, Mario must use the extending brown platforms.

Boss Fight
When Mario goes through the door that leads to Larry Koopa, Larry will be in the middle of the room. He will see Mario and jump in surprise but then he will attack. Larry attacks by blasting bolts of blue magic from his Magic Scepter at Mario in an attempt to hit him. Mario must dodge those attacks and get close enough to Larry to jump on his head therefore making him lose a life. Larry will then get into his shell and start spinning around madly trying to hit Mario. He will then try to jump on Mario so Mario must avoid him. If Mario dodges these two attacks then Larry will start shooting magical blasts again and Mario can jump on his head again. Jumping on Larry's head three times defeats him and wins Mario the level.
