A kid ninja shows up at your house and just... stays there, treating mundane Japanese suburban life like it's a covert ops mission. The comedy lives in the gap between Hattori's absolute commitment to ninja protocol and the fact that his biggest challenge is homework, not assassination. Watch this if you want pure slapstick that doesn't need a plot to justify itself, just a ninja kid and the ordinary world refusing to take him seriously.

A brief Ninja Hattori-kun outing, originally shown as part of a triple feature alongside two other animated films in 1982.
