Percy was still a cheeky engine and often liked to play jokes on Gordon and James, but one day the other engines got their revenge when Percy failed to recognise a "backing signal". After this, Percy was subject to bullying from the big engines until Duck and Oliver arrived and helped Percy to put the big engines in their place.
With Duck and Oilver's arrival, Percy was sent to help in the yard and has stayed there ever since as a goods engine.
