Trouble Bugs are a race of living fireballs that jump out of Oil Drums. Trouble Bugs were enemies found in the original Donkey Kong, and have only appeared there since. They usually chase Jumpman up the level, following his path. Contact with one will cause Jumpman to lose a life. They appear in the Super Smash Bros. Brawl stage 75m as well, which will burn anyone who touches it, and will send the player flying in the opposite direction that they touched the Trouble Bug on. Contrary to their name, they are not bugs at all, but instead a small walking fireball.
