One ordinary Tuesday morning, Emilka and her older brother Kuba were getting ready for school. Their dad, a dentist, always told them not to forget to brush their teeth thoroughly, especially after breakfast. On that day, Kuba, as usual reluctantly, swiped his toothbrush a few times and wanted to rush off to school, but Emilka stopped him at the bathroom cabinet. - Kuba, look what's here! - she called out excitedly, pointing to an empty toothpaste tube that was lying overturned under the sink. As soon as they picked up the tube, suddenly the room lit up with a strange coloured light. In a second they began to shrink until they had shrunk to the size of tiny worms. Before they had time to scream, they were sucked inside the bathroom cabinet, which turned into a whirling tunnel slide. After a moment, they landed softly on something that resembled a huge white cushion. They looked around and were surprised to see that they were standing among giant teeth that lined up in even ranks like an army. Above their heads hung a rainbow-coloured toothbrush as big as a school bus. Suddenly an undersized creature in a white apron, with round glasses and a dental beret, holding a giant floss, jumped out in front of them. - Welcome to the Kingdom of Toothland! - he greeted you with a bow. - I am Doctor Dandelion, chief guardian of the Kingdom. I'm very glad you've come, because right now we need help! For several days now, there has been a band of Vanity Bugs - invisible bacteria that want to take over our kingdom. They are attacking our teeth, making dangerous holes in them! Emilka and Kuba looked at each other with horror and fascination. They did not yet know how they could help, but they were sure that this would be no ordinary adventure. Doctor Dandelion led them between their teeth towards the most damaged tooth, where something strange was just starting to happen.... A sticky, dark mist was appearing from within, pulsing and humming ominously.... Cuba reflexively grabbed the giant toothbrush, while Emilka armed herself with shiny dental floss. Before they could even take a step, a buzzing army of Vanities emerged from the mist, taking on ghostly shapes.... What will Emilka, Kuba and Doctor Dandelion do when they come face to face with the bacterial army?
