Can a hamster, a rat, a turtle, a rabbit, a chinchilla, and two dogs take part in a detective investigation? The kids—Petya, Katya, Vika, Olya, Sashа, Kostya, and Rita—didn’t even ask themselves that question. They simply brought their pets along for a very unusual case: to prevent a carefully planned crime. But no matter how quickly they rushed, trouble still happened! An old lady’s collectible toy was stolen. But the criminals didn’t stop there—they went to the owner of another valuable toy. And while the kids were busy with that… someone had started to keep an eye on them. Will the young detectives manage to bring the villains to light? And what does one very famous bear have to do with it?
