About the adventures of a stray dog Tishka, who became an experienced detective in Lost and Found.

A basket of eggs arrives at the lost and found office. The dog sets off in search of the mother bird, who turns out to be a crocodile.

About how the Lost and Found Bureau staff found the items that had gone missing from the Bureau and discovered the culprit behind these disappearances—a thieving magpie.

The magpie that stole Tishka the dog's medal organized a school of “magpie sciences,” where it decided to teach first graders the “art” of deception. But Tishka and his friend the parrot tracked her down.
