The main character was a small, grumpy wizard who put a spell of gloom on the kingdom of the Princess Dawn. The Princess and her friend Terry Dexter (a boy from the "real" world) searched for the Cave of the Whispering Orchids to find a crystal key to break the spell, while the Grump tried to stop them. In each episode the Grump flew a dragon named Dingo, chasing Terry and Princess Dawn. This led them to bizarre places with strange characters, such as the Blabbermouth of Echo Island, where the mountains were made of living Swiss cheese.
