World 8-Tower (New Super Mario Bros. Wii)
From the Super Mario Wiki
This tower is the first level to feature Fire Bars. There are also moving rocks that can easily crush Mario and make him lose a life. Magikoopa is fought at the end, where he uses his magic to make the battle room's platforms move to the left. Magikoopa teleports often while the platforms move. His magic transforms one platform into one or more enemies. Enemies can vary between Koopa Troopas, Koopa Paratroopas, Goombas, Bob-ombs, Monty Moles, Thwomps, Buzzy Beetles, and Spinies. An occasional Super Mushroom may also pop up, as well as Coins.
