Cannon Box Blast!

Cannon Box Blast! is an official course in Course World in Super Mario Maker 2. It is the fifteenth level of Ninji Speedruns, running from December 8, 2020 to December 15, 2020. It is set in the desert theme for its main area and in the sky theme for its sub-area, as well as in the Super Mario 3D World game style.

Layout
The level begins with a Warp Pipe spawning Cannon Boxes, which Mario must grab to blast through some Brick Blocks and two Ant Troopers and take two Clear Pipes, collecting the first Pink Coin along the way. Afterwards, Mario must hit two sets of ON/OFF Switches near a Big Koopa Troopa to reach the second Pink Coin on the higher path, then take another Warp Pipe to the right of two Horned Ant Troopers. Mario must then travel through a series of ! Block structures and Big Parabones to the third Pink Coin and a Dash Block to another Warp Pipe. Mario must then travel on some Conveyor Belts and hit more ON/OFF Switches to ensure that a red POW Block makes its way across another set of Conveyor Belts, then use said POW Block so that it destroys a Big Thwomp and thus allow Mario to collect the fourth and final Pink Coin and thus enter a nearby Key Door. Mario is then immediately led to the Goal Pole.

Description
"Blast your way through this course with the Cannon Box, collecting Pink Coins along the way! Beware that firing a cannonball will slow you down, though, so consider your shots carefully, and try to blast what needs blasting in the most efficient way possible."
