King and Kayla and the Case of the Lost Tooth

Kayla lost a tooth. She put it in the special pocket in her tooth fairy pillow and now her tooth is missing! If she can't find it, the tooth fairy won't come. Analytical Kayla retraces her steps, searches everywhere, and questions Mason, who rode home from school with her. Sensitive King wonders why Mason smells like a tooth. Could he have Kayla's lost tooth? Or should King take another look at the tooth fairy pillow?
