Scooby-Doo! Who's Watching Who?

It wasn't long until the show's manager, Mace Middlemost, brought Mystery Inc. on as rivals against GSI. After the "Ocean Land mystery", warmed up to Fred and the others, until Mace told him that Mystery Inc. was replacing GSI.

In the end, Scott and his group arrived with the Scooby gang, at Wolf's End Lodge. He, with the other GSI, was suspected to be the "Ghost Hunter Haunter"; it turned out to be their own manager. Scott admited that GSI wanted to be like Mystery Inc. and Fred gave him an ascot.
