Then a Slenderman showed up and terrorizes the waterpark Mindy, Vanessa, Katie, and Vicky went to fight him.

Then, Mystery Inc. showed up to the waterpark to have a splash of a time, but they had to cancel because of what the Slenderman did to the park as they see Tracey and the others fighting the Slenderman as it manages to get away when Mystery Inc meet Tracey and the kids as Fred reveals that he is a big fan of the Gammas when Velma asked them where is Starman, Starwoman, Toby, Samantha, NightBird, Akiko, and Black Dragon as Tracey explains that they are at the southern point of Mexico with H.E.A.T. fighting a giant dinosaur bird while they join forces with Mystery Inc. to solve the Slenderman mystery. Then, Katie caught the sight of Shaggy and then she falls in love with him as Shaggy was a little nervous about it as Scooby and Dakota laughs about it.

In the meantime, Fred, Daphne, and Velma take a look at the crime scene and notice something on the ground, a bill from the Tokyo Glove City store and white powder while they, Tracey, Vicky, Vanessa, Nini, and Birdgirl have a talk with Ms. Klean if she knows anything about the Slenderman as she tells them that Slenderman has been sighted in a forest near Mount Fuji.
