[3] The Princess and her friend Terry Dexter (a boy from the "real" world) searched for the Cave of the Whispering Orchids to find a magic crystal key to break the spell, while the Grump tried to stop them.

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.

The Princess had a pet named Bip — a vaguely doglike creature with tentacular legs, that sniffed clues like a hound dog, turned around by pulling in its tail and head and popping them back out at opposite ends, and communicated in the sounds of a soprano bugle.

The Grump's Dragon was similar to Sam's in Knighty Knight Bugs, including the fiery nasal explosions upon its master.

The series was called Ahi viene Cascarrabias in Spanish and was retransmitted into the 1970s and well into the 1980s by Televisa, in Mexico, with another rerun in 2006 after the DVD set was launched.
