There's something different about a new teacher in the school - Mr. Batrachian. He wears a brown leather suit and his eyes bulge out permanently while his tongue is always long and slimy. All the kids like their new teacher except for Joey and Nate who want to know the truth about the man. They know that he's mean. They know that he's creepy. And they know that sixth-graders are his favourite snack.

The kids at Edgar Allan Poe High School must face off with a mummy.

Sarah has a new friend named Lobo but she does not know that he is a werewolf. Fitz and Brian are suspicious about Lobo's strange behaviour and they discover that Lobo, under a spell, changes into a beast and howls at the moon on a full moon.

Fitz is uncontrollably transforming into an insane monster wreaking havoc all over.
