Children's animation. Chuggington is a special place where the trains are known as chuggers. They talk, think for themselves and don't need drivers. Ride along with young trainees Koko, Wilson and Brewster as they embark on new adventures, make new discoveries and learn the true meaning of friendship. Everyone loves Frostini, the cool Italian ice-cream chugger. Wilson wants to be just like him, so he is especially excited to learn that Frostini needs a helper for the school holidays.
