RIonny-Children's Book: Fun and Learning with Looky and Professor Puzzle

Two stories about the little tooth fairy and the little dummy fairy. Interesting facts about our teeth and dental health. Semi, the little dummy fairy, was just going to work. For many years, it had been her task to collect the dummies from the children and replace them with something beautiful. Most children gave up their dummies at between two and four years old, all by themselves, and therefore Semi did not have much trouble replacing them. But then she had to go to the little Anna.... "What does the tooth fairy really do with the teeth?" Ronja wanted to know from her mother. But as she did not give an acceptable answer, Ronja tried to find the answer by herself. Will she succeed?
