Norbert Nipkin and Grog, scolded and scoffed at by their parents who refuse to believe that the pair have become friends, set off alone to find and solve the final mystery of the Magic Riddle Stone. On the way, they meet delightful characters such as Wag and the brothers Numb and Skull, but they also must deal with the Marsh Monster.
