After being jailed for solving another mystery, the Mystery Inc. gang stumbles upon yet another mystery: A slime Mutant that lives underneath the town and is cocooning anyone who gets in its way. Meanwhile, Velma is trying to get Shaggy to be more intimate in their relationship, however he feels it should be kept a secret as he doesn't want to hurt Scooby's feelings. Daphne keeps hinting her romantic feelings towards Fred who is oblivious to almost everything apart from solving mysteries. The gang are scolded by their parents and are told to stop solving mysteries but the scoldings are ignored. A new dessert bar has opened called Fruitmeyer's and the Slime Mutant seems to be made out of the tasty dessert. No copyright intended for enjoyment of scooby doo fans lol
