The Crass Unicorn:
Billy tells how his day at school went. The kids did terrible things to him, including taking his lunch money (even Harold wanted Billy's money), calling him a loser, and suggesting that he sell himself to science. Billy thinks that Grim and Mandy are not being positive, so he wants to go to a magical place. Grim transports them to the Enchanted Forest. Billy likes the forest, until he meets a rude unicorn named Mary Frances. He wants to change her attitude, however Mandy warns him that he cannot force change on someone. Billy tries this anyways and when he uses psychology, Mary suddenly receives a vision about why she is so mean. It started when darkness came to the forest (this is when the show premiered). The unicorns tried to flee by swimming in the water. Mary could not go because she couldn't swim. After hearing the story, Billy teaches her to swim. Mary believes she is ready to swim with the other unicorns and walks to the place where the unicorns fled. They come back and make fun of Mary Frances, which is similar to the way the students at school make fun of Billy. Mary becomes sad and kicks Billy in the head. Billy wakes up and doesn't remember anything so they replace Billy with Mary. Mary asks Grim to pass the popcorn. Meanwhile, the unicorns poke fun at Billy and he now enjoys the Enchanted Forest. One of the unicorns pops his float with its horn and he drowns.
