Mrs. Snodgrass is introducing the great classic ""Frankenstein"" to the class just as Lydia arrives with a bulky new addition to her braces. Teased about her appearance, Lydia is made to feel like a monster by the other children. Earl, inspired by the genius of Baron von Frankenstein, decides to morph the school into a Bavarian village, complete with a deadly and ferocious monster. Raticus is sent out to retrieve body parts for Earl's creation, but he substitutes a big wad of bubble gum for the creature's brain. The monster turns out to be sweet, bumbling and misunderstood instead of fearsome and dangerous. Lydia and the monster, both feeling outcast because of their looks, have to prove to the others that you shouldn't judge a person based on their appearance.
