The monsters trained by the Clowns compete with each other to be the best, and the best one out of all of them is selected as a new combatant for Nightmare's army.
The Training Clowns come in different shapes and sizes and wield different weapons. The pink-skirted clown with the whip runs the flower class, the large clown with the flail runs the star class, the skinny clown with the three-pronged trident runs the moon class, and the blue-haired clown with the bendable rapier runs the snow class. For some reason, the Flower Teacher is the scariest and the Snow Teacher is the least scariest when it should be the other way around.
