The woman says that Wanda probably would have gone to the underwater caves . They arrive in the cave and Shaggy bursts out of hiding and commands Velma to stop . Wanda sets her monsters on the gang, and while Scooby, Fred and Daphne run for their lives, Shaggy stays back and tries to help Velma fight the witch . </P> <P> Meanwhile, Fred and Daphne reach a dead end . The lake monsters then burst through the wall . At the same time, Shaggy tries to save Velma by singing her favorite song . Velma joins in, and manages to break free of the witch's control . The ghost of Wanda tries to grab her staff, but Scooby Doo arrives just in time and smashes it into a rock, destroying Wanda . Fred and Daphne, who are about to be killed and are clutching one another for dear life, see the monsters turn back into frogs . They run back to Shaggy, who is confessing how much he really likes Velma .
