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...
But now I'm curious about 
what he does and who he sees.
ولكنّي أشعر بالفضول الآن
.لما يفعله وما يراه الآن
Ich frage mich, was er mit
den anderen immer treibt.
¿Cómo socializará con los demás?
¿Cómo socializará con los demás?
Mais maintenant,
je suis curieux de le savoir.
Ma adesso sono curioso di sapere
cosa fa e con chi si vede.
E com isso eu tive interesse em
saber como são essas atividades.
А теперь мне стало любопытно,
что он делает и кого видит.
