Brewster's Little Helper / Jet Pack Wilson

S1 E306: Brewster's Little Helper: Zephie admires the ‘big’ chuggers, and wants to pull freight just like them. Brewster is dismissive when she offers to help him - you have to be big and strong to do the things he does. Jet Pack Wilson: The trainees are thrilled to be spending the day training with Action Chugger. He puts them through some intensive stamina exercises, but Wilson just wants to get to the bit where they use jetpacks and fly.
