Wheelie World is a land inhabited by the Wheelies. Long ago this land was full of happiness and laughter, until the wicked witch Fenella arrived and set up home in Spout Hall - a kettle - on the outskirts of Wheelie Kingdom. Casting her evil spell, the colour faded from the land, the laughter was silenced, and the Wheelies became sad and dejected. Then one day a large, brightly coloured egg arrived and from it emerged a strange and wonderful creature - Chorlton, The Happiness Dragon. As joy and laughter returns to Wheelie World, Fenella now spends her time trying to defeat and destroy the happiness that Chorlton radiates to all. Join Chorlton and his Wheelie friends in all 40 exciting episodes. You'll burst with happiness... and that's gradely!
