As summer vacation draws near, the Mystery Inc. crew heads to Erie Point for a set of summer jobs at Uncle Thorny’s country club, hoping the gigs will help cover the costs from a recent mystery. The club’s opening party takes a dark turn when a frog-like monster attacks the crowd, pushing the team to investigate. Their first stop is the lighthouse keeper, Elmer Uggins, who holds a photograph of the lake’s elusive menace and shares the old legend: Wanda Grubwort, a moonstone-powered witch, warned settlers to stay out of her land. Before she was burned at the stake, Wanda reportedly used a magic staff to twist a frog into a monster that haunted the villagers who ignored her warning.
Velma brings security footage showing the lake monster encounter a cloaked, enigmatic figure on the beach the next day. The team studies the clip to reveal the face, but the moment is spoiled when Velma accidentally spills green tea on the computer, destroying the footage. Tensions rise as personal dynamics complicate the mystery: Fred and Daphne grow distant, while Shaggy wrestles with his feelings for Velma, which strains his bond with Scooby.
The following morning, Velma is found unconscious on the beach, and Shaggy notes warts on her hand, a detail she dismisses. After the latest monster attack is announced, [Daphne] notices purple paint on the cloaked figure’s cloak and suggests they revisit a boat spotted en route to Erie Point. Velma agrees to go on a date with Shaggy, and the evening seems promising until Shaggy lights candles with a match, scaring her. He also fumbles a moonstone he meant to give Velma, accidentally dropping it as Scooby tries to cause mischief because he’s been feeling left out.
A visit to the residence of Hilda Trowburg, Wanda’s descendant, confirms a chilling twist: the cloaked figure seen earlier is Velma herself, though she insists she isn’t Velma. Hilda explains that Velma has been possessed by Wanda’s spirit, and the group confronts how their internal squabbles blinded them to the warning signs—warts, a moonstone obsession, a fear of fire, and the way Velma spilled tea to mask her true identity. On Trowburg’s suggestion, they follow Velma to the underwater caverns, where Wanda’s influence drives Velma to turn three frogs into monsters that attack them.
Shaggy tries to reach Velma by singing her favorite song as the monsters close in on Fred and Daphne, and Velma breaks free from Wanda’s hold. Wanda’s attempt to seize back her staff is thwarted when Scooby confronts the danger, destroying the staff and breaking Wanda’s control, restoring the creatures to their ordinary forms. After Velma’s confession and a kiss that clarifies their feelings, Shaggy and Velma decide to stay friends rather than pursue romance, freeing Shaggy to repair his bond with Scooby. Daphne thanks Thorny for saving the county club, and he vows to arrange legal help so the group won’t face future trouble. With the club safe and the mystery resolved, the team officially embraces the name Mystery Inc., marking a fresh start for their sunny Erie Point adventures.
