There are eight different enemies in the underground labyrinth, each one a little different from the others. They move at a variety of speeds, with the fast monsters capable of overtaking Bomberman at full speed. They have varying degrees of intelligence. Some wander aimlessly about the stage, while others hone in on you and stay on your trail when you try to get away. And three of the monsters are capable of passing through the walls effortlessly. They are much harder to destroy, but if you happen to blow up a wall that they are inside of, they will be killed in the process.
