Plot
Lizzy Morris and her younger brother named Luke Morris have been to HorrorLand before and barely escaped with their lives. They thought they would never return, but then they heard of strange happenings in Horror Land. Both Lizzy and Luke decide to check these strange events out and go back to HorrorLand. There, they meet up with six Very Special Guests: Matt, Carly Beth, Robby, Jillian, Jackson, and Julie, all trying to escape Horror Land to another park named Panic Park.

A strange horror from horror land who called himself 'Monster-X' told Lizzy and Luke about the strange events in HorrorLand. He even told them that Panic Park is more horrifying than HorrorLand. (Told at the 'Story So Far..' of The Streets of Panic Park)

During the way, they find Billy and Sheena up a mountain and they ask what happened to the other guest. They tell them that they went to the Tunnel of Hate. The group goes there in canoes and start hating each other and start to fight. This leads to Carly Beth and Julie almost drowning each other. They soon spot another canoe with the other guests (who have had left earlier along with Billy and Sheena and that have gone insane for being in the tunnel too long): Michael Munroe, Sabrina Mason, Britney Crosby, Molly Molloy, Abby Martin, and Boone Dixon. They all get out and must escape.

They later encounter some enemies from the past in a maze Byron led them to: the Egg Monsters, the Haunted Mask, and Captain Ben One Leg. Lizzy and Luke know everything about Horrorland, so they lead the way to Panic Park through the Hall of Mirrors. They get to Panic Park. Then they find out that Karloff Mennis (The Menace) has tricked and trapped them asking for a favor... "Will you stay in Panic Park forever?"
