Ian is still in kindergarten, so he can't go everywhere he wants to go. But he has a robot dog that can go anywhere instead of the owner. This time - into the depths of the forest. And there is a commotion: the lizard's tail has disappeared! What happened? The hedgehog detective takes up the case, and the robopet becomes his assistant. Let's investigate this case together with the heroes! Using the detective's notebook, we will determine which of the animals left the traces. You will also have to make a sketch, redrawing the details from the descriptions of witnesses. And in order to find the missing tail, we need to figure out who owns it! There are too many secrets!

Unraveling the "tail" story that happened on a sunny summer day in the forest somewhere in Podillia, children will learn about the appearance and characteristics of animals, birds and plants.

The book contains augmented reality - videos that were "filmed" by the robopet, so young readers can clearly see the inhabitants of the forest in their natural environment.
