Dory has her first loose tooth, and, with her usual over-the-top excitement, she cannot stop talking about the tooth fairy. Naturally, this drives her brother and sister crazy. But it also sparks a serious jealous streak in her nemesis, Mrs. Gobble Gracker, who wants all of Dory's attention to herself.

But Mrs. Gobble Gracker has decided to steal the tooth fairy's job, and flying around in a tutu from Rosabelle, she heads for Dory's house. It's time for Dory to come up with a serious plan to get the tooth fairy her job back.
