The Snooks (singular!) derives his name from the Danish expression "leaving the Snooks behind" much used by 7-year-old Eigil's parents to indicate somebody's going nuts. This being a live action-cum-puppet animation film, Eigil's own imagination turns the Snooks into an amiable gnome-like little fellow and best friend during a summer holiday. When they are being joined by a cat, the fun really begins.
