This colouring book has many secrets that are waiting to be discovered. It is made of very special paper, because hidden motifs and patterns become visible when you colour them in. So grab your pencils, get set, go. Who's hiding in the bird's nest? And isn't there someone else down there in the green grass? Colourful contours, large colouring areas and playful, initially invisible details promise great colouring experiences and results. For enthusiastic explorers aged 3 and over.
