Everyone knows that a monster's favorite thing is to scare kids. Lorry is no exception. He wants to be the scariest monster of all.

Lorry wants to follow in the steps of his famous ancestors: his dreadful great-grandfather, Scabby Moldbody, who was known for making kids scream the loudest, and his gruesome great-grandmother, Henrietta Fang, who was responsible for more nightmares than any other monster.

There is only one tiny problem: Lorry is cute, and kids aren't afraid of cute little monsters. Being a different monster makes Lorry sad and ashamed. Unable to fit in, he learns how to stand out.
