Scooby-Doo! Mystery Incorporated

A rash of strange crimes occurs when a number of prominent Crystal Cove citizens destroy the things they love most! A car. A house. A food empire. The gang investigates and soon discovers that each of these citizens had a dream wherein the Dreamweaver, a horrible goblin-king, told them to do it! Meanwhile, with Daphne back in Mystery Inc., the gang doesn't really need Hotdog Water anymore. She leaves the gang...but she's not happy about it...and she's secretly still working for Mr. E as his spy. As the gang gets deeper into the mystery of the Dreamweaver, they uncover the fact that Sheriff Stone and the three other citizens were avid practitioners of a fantasy role-playing game called "Crypts & Creatures" when they were young. The Dreamweaver was a monster created by then Crypt-Master Bronson Stone! Using their skills, Mystery Inc. cracks the mystery and realizes it's an inside job.

When the strange appearance of a mean goat/man demon named Krampus terrorizes naughty kids all over town, the Mystery Inc. gang decide to look into things. Chasing Krampus all over Crystal Cove, they try to second-guess the crazy, evil goat-man's motives -- and who could be behind the mystery. Meanwhile, the old Mystery Inc. is trying to steal the gang's three pieces of the Planispheric Disc while our heroes are distracted by Krampus. The gang finally captures Krampus only to reveal that its Charlie, the Haunted Robot. Someone is controlling the robot... but whom The old Mystery Inc. succeeds in stealing the gang's three pieces and now has the whole Planispheric Disc...or so they think. When Pericles and Mr. E. go to get their three pieces out of the vault, they find it empty! Our gang has stolen the pieces instead.

Traveling through the underground caverns, our heroes trail Pericles and company. They soon learn why they've been collecting all four keys on their final journey down to face the Evil Entity. Reaching the treasure chamber before Pericles, they set about destroying the Evil Entity. But, they stop when the Evil Entity speaks to them. Revealing a secret that could change their lives forever.
