A girl nicknamed "Paingy" invites Tama and Takeshi on a treasure hunt. For some reason, there's a cat that looks like Tama on the treasure map. But all of it is a plan put in place so that Paingy can tell Takeshi something important.

Takeshi is staying home from school because of a fever. Before he knows it, he's hanging out with Tama and the others. The sights and experiences of Third Street from the perspective of cats and dogs is vastly different from what he knows...

outras pessoas nos vissem!
Мы же не хотим, чтобы нас увидели.
