Choomba

Kikanbō are a kind of giant Goomba found in the game Mario & Luigi RPG 3. They have metallic black bodies, red eyes and a chimney on the top of their heads. They are associated with Coal Ants, which will jump into a Kikanbō's head during battle to make it attack more. A Kikanbō will charge up its attack by walking back and shooting smoke out of it's head showing either a shell or a fist; the smoke will appear in a different pattern each time. The Kikanbō will then charge into Bowser, who needs to withdraw into his shell when Kikanbō jumps on him and needs to punch the Kikanbō when it runs into him.
