We all know that tyrannosaurs are big, scary, and not at all friendly. So, when a platypus egg, belonging to a peaceful herbivorous dinosaur, ends up in the nest of a tyrannosaurus mother, we are sure that a great mix-up will follow!

When the little dinosaurs finally hatch from the egg, the sibling platypuses call it Stalitsa, because it is a little drop, and all it wants is a quiet life by the river, munching on its water grasses...

A very funny story with a rhythm from beloved Julia Donaldson and the multi-award-winning David Roberts.
