The Fairy Ring - S1.E17

A strange circle appears on Percy's perfectly manicured lawn. He urgently calls on Gordon for advice – "just mushrooms growing from an old tree stump," says Gordon. But Rosie Gnome knows better: Percy has been greatly honoured…it’s a fairy ring and there will be a big dance tonight! But then the fairies start arriving, and they aren't quite the delicate, feminine creatures everyone has expected. These are cool fairies, with rock guitars and heavy sound equipment. Overwhelmed by the destruction the party will cause, Gordon negotiates with the Fairy Queen to limit the damage to Percy’s lawn. The Chief Gnome attends as guest of honour and even Percy discovers it’s possible to have a great time.
