Tuck, Clutch, and Nip escape from Dunwyn Castle's dungeon again. Cubbi finds their lost treasure map and takes Tummi to look for it. They use the Gummies' tunneling Mole machine to remove rocks an avalanche blocked the treasure with, but are caught by the trolls who steal the Mole to steal Calla's crown jewels. The Gummies are left to figure out how to get it back so the robbery doesn't occur and humans don't get a hold of it or learn whose it is either.
