Kooky

Kooky (Czech: Kuky se vrací, literally "Kuky returns", a pun on Lassie se vrací) is a 2010 Czech action comedy film directed by Jan Svěrák. The film combines techniques of puppet animation, stop motion and live action. It tells the story of a six-year-old asthmatic boy whose parents throw his favorite toy away, an old teddy bear named Kooky. The boy, however, secretly sneaks out of the house at night (without his boots and being dressed only in his pajamas), to retrieve Kooky from the garbage can and bring him back home. Due to that, the boy gets ill. In his feverish dreams, Kooky comes to life in the landfill, escapes into a mysterious forest and begins its journey amongst the rough-and-ready creatures of the forest.
