Crayon Shin-chan: Burst Serving! Kung Fu Boys ~Ramen Rebellion~
What they share
Both films are directed by Wataru Takahashi, and they both carry the playful mood tag, and they sit in Adventure / Animation / Comedy territory. If that's the register that drew you to Crayon Shin-chan: Fast Asleep! Dreaming World Big Assault!, the second film will land in a comparable space — through a different lens.
playful
What Crayon Shin-chan: Burst Serving! Kung Fu Boys ~Ramen Rebellion~ is
One more for the pile of movies where cartoon characters try martial arts. Shin-chan and the Kasukabe Defence Force learn a new style of Kung Fu in Aiyā Town. It probably seemed like a good idea at the time.
