K9 Cannon

K9 Cannons are a species of floor-mounted cannons in the shape of Noobis. They appear in Poobah the Pharaoh's Pyramid, a level in Wario: Master of Disguise. K9 Cannons attack by shooting small orange balls at Wario. The name K9 Cannon is seemingly based on the word canine, which is the scientific term used for dogs.

In-game Description
