Hannah and Olly have just moved to Golden Valley Farm. One day, they make an amazing discovery: when they spin the scarecrow's arm . . . whoosh! . . . they find themselves on Magic Farm, where nothing is quite what it seems! The chickens are multi-coloured, the pigs' tails have to be curled and the scarecrows can walk and talk! The Hayseeds, the friendly scarecrows who look after Magic Farm, are having a spot of bother with the naughty Little Rotters, who just love to cause trouble. The children are determined to help their new friends!
