Living solo in his recently-monster-infested town, 13-year-old Jack will have to think fast, find friends, and get creative if he wants to survive and defeat the towering Blarg!

"When Jack sees his friends arguing, he believes a new quest will pull the team together, so he takes Quint, June, and Dirk to the mall... on a quest for fun! But danger lurks beneath their feet. Literally."

Thrull takes the kids to meet the many talking monsters living at Joe’s Pizza. They learn that Blarg, the giant monster the kids slayed, was a servant of Rezzoch, the trans-dimensional villain who opened the monster and zombie portals to Earth.

The kids set out to fill Thrull’s bestiary with photos and the essences of various monsters, and Quint tries to use this opportunity to prove his worth to the team.

After being cornered by an undead bowling league, the kids are saved when The Shrieking begins again and the zombies stop dead (ha) in their tracks to follow it.

After Thrull confides in Jack that the only way to defeat Rezzoch is to complete the Bestiary, Jack is worried that he might not be up to the task of protecting his friends and looks to Thrull to train him.
