Bowser's Bob-omb Brigade

Bowser's Bob-omb Brigade, or World 6-, is the last level of World 6 in Super Mario 3D World. It is unlocked via completing Fuzzy Time Mine, and its own completion frees the light blue Sprixie Princess, who builds a Clear Pipe to Motley Bossblob's Big Battle. This level autoscrolls.

Layout
The level starts with the player near some Blocksteppers and a tank with a Fire Bro. After avoiding some more enemies, tanks, and obstacles, the player can find a pipe on top of the last tank in the level. Entering it leads to the boss battle with Boom Boom, who after defeat, drops a Warp Box and a circle of Coins. The Warp Box leads to an area with the Goal Pole and the Sprixie Princess.
