S3·E13 Wobbly Wheels

It's a busy morning in Chuggington, Piper is called to the main depot. Pete helps her as she is still very wobbly on her wheels. Piper is given her trainee badge and Pete takes her to the park for some training. Wilson, Brewster and Koko are doing some safety training with Skylar in the mountains. They are learning how to use the chug catcher.
