Crystal Cove may be the Most Haunted Town In The World, but that doesn't stop Scooby and the gang from trying to prove that most of its most famous tourist attractions were fakes much to the anger and dwindling profits of their parents.) But when a Radioactive Barrel is accidentally opened releasing a hideous Sewer Beast that cocoons it's victims in frozen yogurt, their mystery solving skill are put to the test. After all, what could a sewer beast, a delicious edible dessert, underground caves, and shrimping boats made of balloons possibly have in common? I'll give you a little hint... the local bank.

A long time ago there was a town called Gatorburg, where alligators swam wild and free - and people got rich. Now, it's a ghost town. The reptiles have all disappeared. But when Scooby and the gang receive an imitation Gatorburg purse, they decide to see for themselves if the beasts really are gone. Forced to spend the night when someone steals the engine to the Mystery Machine, they soon discover that the gators have indeed returned ... only these swamp creatures have comb-overs, walk on two legs - and don't like visitors!

A mysterious GHOST TRUCKER is terrorizing Crystal Cove. Add to that all the doorknobs have begun to disappear from around town, someone has hidden a priceless diamond, and Fred's dad the Mayor is up for reelection against a guy named Avocados, and Scooby and the gang have their hands full. Oh, and did we mention that Daphne has been set up on a blind date with a pinhead named Rung Ladderton, who... wait for it-- sells LADDERS for a living.

While hosting a volleyball tournament for TRICKELL'S TRIQUID diet moisture, a smooth drinking beverage that's just like water except not so fatty, Crystal Cove beach finds itself attacked by a hideous MAN CRAB who has taken a liking to the tournament's female players. Desperate to stop this beast before it scares away all the tourists, the gang investigates, convinced it is a disgruntled local named SKIPPER SHELTON (famous for his delicious clam filled waffle cones, his missing nose, and his hatred for Crystal Cove beaurocrats.) But when Daphne is captured by the Man Crab, Scooby and the gang have to put the mystery solving into overdrive or risk losing not only Daphne... but the sanity of their leader Fred who is not taking the abduction well.

A hideous creature named Que Horrifico is turning the children of Crystal Cove into monsters. The adults in the town are in shock, reacting in the only way they know how - by abandoning their children and running away! Only Scooby and the gang stay behind to solve the mystery. Going undercover as a family - Fred as the dad, Daphne as the mom, Velma as Grandma, Shaggy as the son and Scooby as the baby - the gang rents a house in order to capture Que Horrifico. But when their plan backfires, and Que Horrifico uses his power over the monster children to cause them to attack the gang like something out of a horror film, it looks like all is lost. That is, until a cartoon character named Broccoli Head comes to their rescue. That's right ... Broccoli Head!

There's a new girl at Crystal Cove High named Alice May and she's set her romantic sights on Fred. Only one problem... ALICE IS DEAD! That's right, Fred's new girlfriend is a dead girl. Alice is a ghost, famous for snatching up guys like Fred and disappearing with them forever. Now she wants to take Fred to the prom, which means he's next. Fortunately, Daphne also wants to go to the prom with Fred and she's not going to let Alice beat her to the "punch" bowl (wink-wink). And what about the rest of the gang? Well they've got problems of their own. See, Velma wants to go the prom with Shaggy, but Scooby wants Shaggy to watch a Vincent Van Ghoul marathon with him. You keeping up? Good, because this one is going to get nasty, and when it's over... Scooby and the gang will never be the same again.
