Percy

Percy is a green saddle tank engine who was brought to Sodor to help run the railway during the big engines' strike. He is one of the youngest engines and is quite cheeky, often looking to trick or tease other engines, sometimes getting him into trouble. Percy's favourite job is to deliver the mail and he works on Thomas' Branch Line as a goods engine.
