Layout
This is a horizontally autoscrolling level. The player starts at the forefront of a battalion of moving tanks. The tanks are lined with cannons that fire either cannonballs or Bob-ombs, some have Burners on the front, and others have Rocky Wrenches. There is also a Giant Cannon that fires Giant Cannonballs before the Warp Pipe at the end of the level, which leads to a chamber with a lone Boomerang Bro. that will end the level upon being defeated.

Additionally, the original game and the Super Mario All-Stars remake have thirteen tanks, whereas the GBA remake has ten.
