What they share
Both films are directed by Wataru Takahashi, and they both carry the playful mood tag, and they sit in Animation territory.

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.
