One morning Tosia woke up with a strange feeling that something unusual was going to happen today. As she ate her breakfast and walked over to the mirror, she saw a tiny door on the mirror that had never been there before! The door was as white as milk and had a handle shaped like a toothbrush. Tosia knocked gently and the door immediately opened. Behind them stretched a great land - Tooth Castle - and the smell of fresh mint was in the air. There were funny creatures roaming around: the Teeth - white-faced, smiling and very playful. Tosia made friends with the Toothies, who showed her a huge, glittering castle built from crowns of snowy teeth. Suddenly, a dark cloud covered the sky above the castle. Out of the depths of the forest ran the unfriendly Vanity Monster, who whispered in the ears of all the Toothies: "No need to brush your teeth! Forget brushing!". The Toothies began to freak out and the castle piece began to turn grey and dull. Tosia looked at Teeth with concern. What would they do now to protect the Tooth Castle from Vanity? A mysterious idea popped into Tosia's head, but.... what could it be?
