Uchitama?! Have you seen my Tama?

Overview

In a city somewhere in Japan, there’s a flyer often seen on Third Street with a picture of a cat with a kinked tail, bearing the words: “Have you seen Tama?” A young boy gazes at the flyer, but he has fluffy ears on his head…!? Watch the dogs and cats from Third Street take on a human form and get up to some mischief. (Source: Kadokawa, translated)
