Chuggington - Season 2 - Eps 16: Chilly Chuggers
An ice storm hits Chuggington and Koko really wants to help. She sees her chance when she comes across one of the anti-freeze cars. She thinks she's de-icing the tracks, but she's actually making them even icier - she doesn't realise that the car contains water. Because of her actions, Eddie and Emery get stranded out in the cold. Koko admits her mistake and does what she can to help Calley rescue them. When Eddie and Emery are back, safe and warm, Koko promises she'll never do anything like that again without checking with someone first!
