{{level infobox

|before_alt=[[Dancing Blocks, Poison Swamp|<<]]

The level starts in a tower with a large [[Snake Block]] and a [[Mega Grrrol]] found behind [[Brick Block]]s. A [[Mega ? Block]] is found above a Brick Block containing a [[1-Up Mushroom]]. The Snake Block and the [[Poison (obstacle)|poison]] begin to rise, and [[Grrrol]]s are spawned from the wall. A [[Red Ring]] is found, followed by another Mega Grrrol in front of a [[P Switch]]. A pair of [[Spinner]]s also appears, and the Snake Block begins to rise. A second Snake Block is then found, followed by the boss door, which takes the player to [[Boom Boom]]. [[Kamek|Magikoopa]] causes him to grow larger before the battle. He must then be hit three times in order to be defeated.

==[[Star Coin]]s==

*'''Star Coin 1''': The first Star Coin is found near some poison at the beginning of the level near a [[Grrrol]] spawner.

*'''Star Coin 2''': The Star Coin is located between two [[Spinner]]s.

*'''Star Coin 3''': The last Star Coin is found in a secret area, with a [[Wall Jump]] needed to get it. In ''[[New Super Mario Bros. U Deluxe]]'', [[Peachette]] can also be used to reach the Star Coin, but she will still need to Wall Jump to leave the area.
