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...
Listen, Tama-chan. There's a 
treasure hidden in these woods.
استمع يا تاما-تشان، ثمّة كنز
.مدفون في هذه الغابات
Hör zu, Tama, hier im Wald
liegt ein Schatz versteckt.
Tama, hay un tesoro oculto en el bosque.
Tama, hay un tesoro oculto en el bosque.
Écoute, Tama.
Il y a un trésor dans le bois.
Senti, Tama.
C'è un tesoro nascosto in questo bosco.
Ouça, Tama-chan. Há um tesouro
escondido nesta floresta.
Слушай, Тама. Где-то
в лесу спрятано сокровище.
