Mr. Trixenstuff unmasked.
The gang asked him if he'd seen Mrs. Knittingham after she was kidnapped by the ghost of Buster McMuttMauler. He claimed he hadn't, but promised to let them know if he did. Upon leaving, he complimented Scooby's family collar, much to Scooby's disgust.
When the ghost was captured, he was unmasked as the culprit. He wanted to steal the Doo family collar and sell it. Scooby wanted to get rid of it by trying to give it him, but was prevented from doing so by Mommy Doo. He was then taken to jail by Mr. Goodman.
