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...
The strange events of today might 
have been a dream I dreamed,
،قد تكون أحداث اليوم الغريبة حلمًا
Womöglich habe ich die rätselhaften
Ereignisse heute nur geträumt.
Seguramente todo aquello
fuera un sueño.
Seguramente todo aquello

Le strane cose successe oggi magari
sono state un mio sogno,
O dia misterioso de hoje talvez
tenha sido um sonho meu.
Может, сегодняшние странные
события мне приснились,
