A mysterious blob shows up at your door and somehow becomes family without anyone asking why. The show doesn't care about explaining what Oochopus is, it just watches two kids and a strange creature learn to live together, quiet and warm. This is comfort television that trusts you to find the whole thing charming without ever needing to justify it. You're not watching a story unfold; you're living in a space where the impossible is just another Tuesday, and that acceptance is the entire point. Kantarou and An-chan don't question their houseguest. Neither will you.

A mysterious lifeform called Oochopus turns up one day at the home of five-year-old Kantarou and three-year-old An-chan. Oochopus is cute, though a bit irresponsible, and the two children welcome it into their household as a member of the family. The TV short series runs for 38 episodes, with Oochopus at the center of it all.
