There are no rules in Moominvalley — or, at least, there aren’t supposed to be. No one can police the wondrous bounds of its nature and the creatures that call the harmonious landscape home. So when a self-appointed Park Keeper and his goon squad of police officers start setting up manicured parks with groomed hedges, gates, and — worst of all — rules, Moominvalley starts to fall into chaos. Everything that was once good and peaceful is disrupted. When Snufkin returns from an adventure in a distant land, Moominvalley is unrecognizable and his best friend Moomintroll missing, having been arrested and tossed into a cage while trying to stop this downfall.
