Twins Judy and Jimmy Barton crawled into their attic one December day and found a passageway to a place called Maybeland. They looked in all the dusty corners for any sign of the silver star that always sat atop their Christmas tree. Their search crossed the path of little Paddy O'Cinnamon, 'The Cinnamon Bear', who had shoe-button eyes and a ferocious growl. He showed them a small hole through which the Crazy Quilt dragon had absconded with their star and invited Judy and Jimmy to pursue the rascal. Paddy would function as a guide and they'd chase the dragon throughout Maybeland. Paddy magically 'de-grew' the twins so they'd fit through the attic tunnel, fired up a miniature airplane powered by soda pop, and flew the Barton kids into a startling and wondrous adventure.
