Percy the Small Engine

Percy is a little green saddle tank engine who was brought to Sodor to help run the railway during Gordon, Henry and James' strike. He is one of the youngest engines on Sodor and he is also Thomas' best friend and is quite cheeky, often getting himself into trouble with his attempts to play tricks on the other engines. Percy's favourite job is to deliver the mail and he works on Thomas' Branch Lineas a goods engine.
