Rock Monster

Two rock monsters that looked like stalagmites lived in Badcarl's Cavern.

Season one
When Shaggy Rogers, Scooby-Doo, and Scrappy-Doo had a picnic in the cavern, the monsters ate some of Scooby's picnic food and then chased the trio. They were defeated when Scrappy splashed them with water and shrunk them to the size of "pet rocks."
