One night in Chuggington, all of the power went out. It was the hottest day of the year tomorrow and if Frostini couldn't keep his Ice Cream chilled, it would all melt. He went off with Speedy McAllister to get some ice from the ice cave while the trainees kept some ice cream in the refrigaration wagons, which run on Chugger power. Unfortunately, Frostini came back with the ice to see that they had fallen asleep and all of Chuggington's ice cream had melted. Speedy came up with the idea of making smoothies with the ice cream and crushed up ice which saved the hottest day of the Year.
