Thomas & Friends S18E13 - Missing Gator

Percy is missing his old friend Gator and begins to mope as he thinks about the times they had together. Percy tries not to think about him, but it only makes the matter worse. Later, when he goes to Ulfstead Castle to take some trucks of sculptures to the docks, they run down the hill and crash into Stephen's mine. To find the trucks, Percy must follow Gator's advice and venture inside, all on his own.
