Someone has stolen X Middle School's beloved mascot, Lobstee the Lobster. Time is running out for both Lobstee and the Bocce Team, and the key to finding him before time runs out might be X's resident psychic, Alistair Greystone.

Duappy, a virtual pet kept alive the longest, has been stolen, and it is up to Fillmore and Ingrid to find X's pride and joy before a reporter comes to X to do a story on Duappy and before Duappy dies.

Four victims—Wilbur, Grover, Becca and Stella. Four bullies—Rochelle, Bryan, Fiona and Horace. Someone's fed up of people being made to feel small and scared and is targeting each victim's bully respectively. Despite not wanting to help bullies, Fillmore starts to investigate who would want to scare the bullies so much. The main suspects are the four victims, but the victim of each bully is proven to have an alibi.
