World 4-Tower is a level found in the game New Super Mario Bros.


The tower includes many Fences, Amps, moving walls and rising lava. Mario or Luigi must navigate their way to the top of the tower to avoid being hit by the rising lava.


As with all tower bosses, Bowser Jr. is the boss. However, his attack pattern has changed; trying to jump on him will cause him to duck in his shell. To defeat him, Mario or Luigi must use Koopa Shells thrown by the young prince, and toss them at him to trip him up, and jump on his belly. This must be done three times to win.

Star Coins

  • Star Coin 1: The first Star Coin is located behind a Fence; you will need to have flipped yourself behind the fence before now. Once you're behind, grab the Star Coin.
  • Star Coin 2: As you climb up the Tower while escaping the rising lava, you will end up on a wide fence with some Amps above it. The Star Coin is in between the Amps to the right.
  • Star Coin 3: The final Star Coin is located in a small alcove. Jump on the sliding stone and duck underneath the ceiling (unless your Small Mario or Mini Mario) and you will end up on the other side where the Star Coin is. Jump up, grab it, and duck back to the other side before the lava catches up to you.
