 The story was set in fictional Medfield, a town that (along with its eponymous Medfield College) was the setting for five other Disney gimmick comedies, including "The Absent-Minded Professor," "Son of Flubber" and the “Dexter Riley” trilogy ("The Computer Wore Tennis Shoes," "Now You See Him Now You Don’t," "The Strongest Man in the World").The mythology of the Borgia ring was changed from the first film, in which young Wilby read the inscription on the ring once and then was the victim of random transformations which could only be stopped if he performed a heroic deed.In this sequel, he simply turned into a dog whenever the ring's inscription was read aloud, and the spell would generally last from five to ten minutes.
