Outward Bound Olwin / Old Puffer Pete's Surprise

S1, E220: Olwin takes every group of new trainees out on an outward bound training course. The trainees get fed up when she treats them like babies and they go off and hide from Olwin in the Old Town. It’s all fun and games until a heavy fog rolls in, and the trainees are trapped! / Old Puffer Pete has been working in Chuggington for 150 years, and the mayor wants to commemorate his anniversary with a special show. The trainees are going to do a carefully choreographed routine - but it all goes wrong. Wilson doesn’t listen, Koko goes too fast, and Brewster doesn’t seem to know his right from his left! Will they be able to master their moves in time for the show?
