A lot of hedgehogs have already been transported from Evan Island to the mainland. But hunting dogs continue to track down the spiny animals. It turns out that there are those who believe that hedgehogs have no place on this territory...

It's good that Mr Dog's thirst for adventure and the hunt for pleasant memories led him to Evan Island. Here he finds a new friend, saves him from sniffer dogs (although this turns out to be an unfortunate misadventure) and tries to find out why hedgehogs are actually being caught on the island. Now Mr Dog's kind paws are in charge of protecting little Koluchka and helping him to build a new life.
