Coalbit

Coalbits are little insects made out of coal from the game Mario & Luigi: Bowser's Inside Story. They assist Choomba in battle. Coalbits don't really attack at all when fighting Bowser. They do attack the Mario Bros., though. They jump into the head of a Choomba to make its attack more powerful. Bowser can inhale Coalbits and let Mario and Luigi battle them. They attack by using their snippers and trying to tackle into them. Coalbits usually appear in groups. If Bowser defeats the Choomba that's with the Coalbits, they will run away.
