Crayon Shin-chan Gaiden: O-o-o no Shinnosuke

In a quaint rural town, peculiar occurrences have recently become the norm, drawing the attention of its quirky residents. Among them is the youkai kindergartner, O-o-o no Shinnosuke, who, alongside his youkai father, Tamatama Dad, arrives with a mission: to locate the elusive Big Butt Mom, who has mysteriously vanished from home. Their search leads them into a series of unexpected and humorous adventures that intertwine with the town's unusual happenings.

When Fumie Sakura, a local elementary school girl, becomes the target of a bizarre creature known as Fuzzy Wuzzy—a youkai characterized by its excessive hair—Shinnosuke leaps into action to help her. This fateful encounter marks the beginning of an extraordinary investigation into the supernatural phenomena plaguing the town, blending comedy with elements of the supernatural as they delve deeper into the world of youkai and uncover the town's hidden secrets.
