Ember, a friendly dragon, is searching for someone to play with when she stumbles upon a sad bear named Grizzle, who has lost his smile. Together, along with a shy mouse named Pip, they search for Grizzle's smile. Along the way, they encounter other forest creatures in need of help, and the trio is more than happy to lend their assistance. Will Grizzle's smile be too hard to find amidst the adventures, or has it been hiding somewhere close all along?
