Snake Block Tower

Snake Block Tower, or , is the Tower of Soda Jungle in New Super Mario Bros. U. This level is unlocked via completion of Bridge over Poisoned Waters or Bramball Woods. Beating the Boom Boom in this course unlocks a passage to Which-Way Labyrinth.

Layout
The level begins in a small, one-screen room where some Giant Brick Blocks and one Giant Question Block are found. A Warp Pipe takes the player to the second area of the tower.

The second area features a giant Snake Block, which goes upwards, coming across Amps and their larger sub-species, Spinners, a Red Ring, a small Snake Block as well as two Star Coins. When the Snake Block clashes with a wall, stone blocks on the ceiling break, thus revealing the Checkpoint Flag.

Another Warp Pipe takes Mario to a similar area, though this time the plumber encounters bigger Spinner rows, and more Big Amps. The third Star Coin is found as the giant Snake Block rises. To the far left is the door to the Boom Boom's room. An Invisible Block hides an item on the wall next to the door. Before the fight officially begins, Kamek will swoop in and enlarge the Boom Boom.
