The Tooth Fairy collects lost teeth from children by slipping under their pillows and exchanging them for small gifts like coins and glitter. She operates at night, using her wand to make windows shimmer like water so she can pass through them. She is as small as a bumblebee, quiet, and prefers to remain unseen.
The Tooth Fairy interacts with animals like owls, foxes, and bats, who recognize and welcome her. She also uses a luna moth as a mode of transportation to conserve energy for her nightly visits to children's homes.
When Natalie speaks to the Tooth Fairy, it surprises her because no child has ever spoken to her before. The Tooth Fairy decides to show Natalie her world, shrinking her to fairy size and taking her on a journey to collect teeth from other children's homes.
The Tooth Fairy's wand can make windows shimmer and flow like water, allowing her to pass through them. It can also extract teeth from under pillows, create glitter and coins, and shrink or enlarge Natalie to fairy size and back.
Natalie is shrunk to fairy size and rides on a luna moth with the Tooth Fairy. She helps collect teeth from other children's homes, uses the Tooth Fairy's wand, and dreams of fairy kingdoms with gleaming castles and fluttering green wings before being returned to her bed.
