This collection of puzzles mainly has a pedagogical purpose. They start from the principle: learning through play.
They are aimed primarily to children aged between 3 and 10 years.
The objects of the puzzles are animals of different categories: insects, amphibians, reptiles, birds, sea and land animals... Most of the puzzles display a single animal, its shape. There are animals in a scene but presented individually. Animals are not photographs but might be considered cartoon characters.
