Crayon Shin-chan Movie 17: Otakebe! Kasukabe Yasei Oukoku

In the seemingly quiet town of Futaba, a new mayor champions ecological initiatives. However, this facade conceals a darker agenda. Mamoru Shizan, the mayor, is secretly the leader of "SKBE," an eco-terrorist group determined to reshape humanity through a transformative serum. When Shinnosuke's parents unexpectedly undergo bizarre transformations – his father into a chicken and his mother into a panther – the family finds themselves thrust into a world of escalating chaos.

Joined by the enigmatic Victoria, the Nohara family and remnants of the local defense force must confront Shizen’s plan to fundamentally alter existence. The series explores themes of environmentalism taken to extremes, familial bonds under duress, and the unexpected consequences of radical ideologies within a uniquely comedic framework. It blends lighthearted action with moments of reflection on humanity's relationship with the natural world.
