"Tooth" tells the story of a feisty young Tooth Fairy who lives in a world called Fairytopia that has lost its ability to use magic. Fed up with the way most fairies have forgotten about magic, she decides to give away all of its money and bankrupt her world, two days before Christmas. When she realises how much trouble she is in, she realises the only person who can help is the legendary Mrs. Santa Claus, who disappeared, along with magic over 100 years ago. Teaming up with two human children and a number of fairies who are living incognito among humans, she sets off on the adventure of a lifetime, pursued by the evil, terrifying fairy Plug.
