Scooby-Doo and the Ghoul School

An evil plant creature servant trapped Scooby, Shaggy, Scrappy, and Matches in a huge well of water. A Giant Well Dweller appeared and it was very large. Matches tried to breathe fire, but the water washed his flames out. Scrappy had a better idea: play ball.

Scrappy, Matches, and Scooby hit the ball and the Dweller tried to hit it. The ball went higher and the monster went after the ball. It was the chance for Scooby and the gang to get out of the well by climbing up its back. Scrappy let the Dweller keep the ball.



  • While they were on the Well-Dweller, Shaggy made a joke that it was a "Dwellevator".
  • It is unknown what happened to the Well-Dweller after Revolta's castle exploded.
