What's New, Scooby-Doo?
The Dinwiddie kids were now teens, and their mother planned a big comeback. During this time the band's old van, the Mystery Machine, (which now belonged to the gang) was acting on its own and causing serious trouble. This was believed to be the ghost of Flash, the original owner, who had come back for revenge. When Mystery Inc. investigated, they suspected it to be Randy due to his study at and his resentment at being overlooked by his more talented siblings. It turned out it was Mrs. Dinwiddie who did it for publicity. She was able to remote control the Mystery Machine and make it look like a monster due to the time she spent "helping" with Randy his homework. It turned out Andy and Mandy weren't interested in being musicians anymore, leaving their mother in shock as they apologized to Randy for making him feel left out.
