Fed up with Gummi Bear stories by Sir Gawain, a retired knight and Cavin's grandfather, a jealous citizen of Dunwyn, Lord Willoughby, issues a challenge to him: Find evidence of the Bears' existence, or give up his entire fortune.
Obnoxious Lord Willoughby makes a risk-everything bet with Sir Gawain that he won't be able to find a Gummi Bear. Cavin can't break his promise and show him Gummi Glen to help so begs the Gummi Bears to step in and help him themselves. But there's an added reason for urgency: Tummi has eaten fruit off a tree that causes anyone to do so to turn into a tree himself and a spell is needed to save him. But the Gummi medallion has fallen off of Zummi's neck while getting him inside and Willoughby has found it, and is set on hiding it so Gawain can't be proved right. The Gummies ask Gawain to team up with them to reclaim it.—brainybrailler@comcast.net
