Choomba

Choombas are a kind of giant, metallic, locomotive-type Goomba found in the game Mario & Luigi: Bowser's Inside Story. Their name is a pun on "choo", a sound effect often associated with trains, and "Goomba". They have coal-black bodies, red eyes, yellow-glowing pupils and a chimney on the top of their heads. Only Bowser can fight these enemies. They are associated with Coalbits, which will jump into a Choomba's head during battle to make it attack more and with greater speed. A Choomba will charge up its attack by walking back and shooting smoke out of its head showing either a shell or a fist; the smoke will appear in a different pattern each time. The patterns indicate the order and types of attacks it will use. The Choomba will then charge into Bowser, who needs to withdraw into his shell when Choomba jumps on him and needs to punch the Choomba when it runs into him depending on what command is shown in the smoke. Choombas also appear in the battle with the Fawful Express. Groups of four of them come out of the Fawful Express to attack Bowser. To counter this attack, the player must tap the area the Choombas are coming at Bowser and stomp them.

Bowser can use the Vacuum Block to inhale a Blitty from Choombas.

Trivia

 * Coding for Choombas was found in the games programming that revealed Choombas were originally able to be fought by Mario and Luigi, and they had smoke signs that smoked an M for Mario or an L for Luigi. It was to be countered with the Hammer.
