Percy is hauling very special cargo! Inspired by the episode, 'Percy and the Calliope,' where Percy is determined to save a rusty old organ – the calliope – from being melted down! Percy races against time to make the calliope play before it reaches the Smelter's Yard! Press the button on the calliope to hear music! Percy and the calliope can connect to other Wooden Railway engines and vehicles with magnet connectors.
