Scared Alot in Camelot

Merlin the evil wizard

After Zarko's the magician's act, the gang traverse to Shaggy's eccentric millionaire uncle Shagworthy's Castle. Camelot, transported overseas stone by stone and rebuilt. However, the ghosts that haunt the castle also seem to have followed. The ghost of Merlin (I thought he was a good guy) and his servant the Black Knight capture uncle Shagworthy, and the housekeeper warn the gang away. The gang persists in searching the Castle, and the fun begins when Shaggy and Scooby become hypnotised into Merlin's Evil (and incompetent) Servants!
8/10 +1 because Uncle Shagworthy is in it, and he's cool.
