Say hello to Bunsen, a new beast in Muckledunk high school. More precisely, he is the first in the world beast at human school. He has a very important task to prove the monsters and humans can coexist despite their differences. Bunsens friend, a boy named Mikey Munroe helps him in doing so. The boy teaches him simple human things. To do a homework, to take it in the dining room and to control his inner little monster which tries to get out sometimes. Bunsen is very curious, and he wants know everything about humans. Along with Mikey he will prove to the mankind that a beast and a human can be the best friends.
