Stella discovers that her new glasses are magic, allowing her to see the knit-knotters--night sprites that are flitting around town tyeing knots in children's hair so they need haircuts--and when a conversation with one of them, Trixie, reveals the reason, Stella comes up with a plan to deal with the mischievous fairies.
Stella hopes to use her magic glasses to see the Tooth Fairy, but instead she sees Piper, the Tooth Bandit, a type of night sprite that steals the coins left for children and uses them to decorate their scooters--so Stella comes up with a different kind of decoration for the bandits.
