A Pup Named Scooby-Doo
He said that if Thorne went to jail for the crimes of Stinkweed then he could get the part. It would be a much better role than his current one, appearing as a "Bucket O'Nachos" in commercials for Mr. O'Greazy. This made him a good suspect to be the monster himself. He and Jane Thursday were both suspected to being Stinkweed, but was found innocent when Stinkweed was unmasked as Vincent Thorne. He was later rehired by O'Greazy to star in a Bucket O'Scooby Snax commercial.
