Baghead was the temporary alias and disguise of Sheriff Bronson Stone.

He had to take a new job at Skipper Shelton's Clam Cabin after being fired by Mayor Fred Jones, Sr. He hoped to hide his shame, but the disguise was completely transparent and the gang had to pretend to be fooled out of pity.
Fred Jones, Jr.: Sheriff!
