Cannon Box

Cannon Boxes are items that appear in the Wii U game, Super Mario 3D World. A Cannon Box is first found as a ? Block but, after being hit once, it reveals a black box with a Bill Blaster insignia on its sides. The players can then hit it once again, causing them to wear it over their bodies. While using a Cannon Box, the characters can fire cannonballs from a cannon in front of it. They also change their color to match the character that is wearing it.

Some Cannon Boxes are also obstacles that keep shooting cannonballs to harm the player. These can be turned into wearable boxes if struck from below or hit with a cannonball. In relation to how to obtain them, and how they are used, Cannon Boxes are similar to Propeller Boxes.
