Aachi wa Ssipak [Movie]

• Anime from South Korea.
  
  In the future, all energy sources are depleted, except human excrements. To reward production, people receive addictive, Popsicle-like Juicybars. Aachi and Ssipak are street hoodlums who struggle to survive by trading black market Juicybars. Through a chain of events involving their porn-director acquaintance Jimmy the Freak, they meet wannabe-actress Beautiful, whose defecations are rewarded by exceptional quantities of Juicybars. For that reason, Beautiful is also wanted by the violent blue mutants known as the Diaper Gang (led by the Diaper King), the police (most notably the cyborg police officer Geko), and others.
