Kluitman Witch Lilly - What a beast

Lilly and her little brother Leon have to look after Rudi, the neighbour's little dachshund. Leon absolutely loves the dog and wants him all to himself all the time. Lilly doesn't like it and also wants a pet of her own to play with. In her magic book there is a spell that could be the solution. Or is there something strange going on with the spell?
