“Three Jolly Fellows” tells of the adventures of three small men in a world that borders on the fantastic: the composed and close-to-nature Mossbeard, the irritable city dweller Halfshoe, and the sensitive poet Muff. An old woman’s inexplicable love of cats has lured many felines to the city. Risking their lives, the diligent and ready-to-help fellows lure the gang of cats out of the city, with the result being trouble in both the city and nature.
