Fan Casting Percy in Thomas and the Quest to Save Sodor.

Percy is the one of smallest engines on the Steam Team. His favorite job in the world is pulling the mail train. His best friends are James and Thomas. He has a wife named Nia, who comes from the far away country of Kenya, Africa. He's a happy little engine who's quite content with puffing around the island and sometimes doesn't like to venture out to the big world outside. But with Thomas's help, he sees that the outside world isn't as scary as it appears. Being one of the younger engines, he gets confused and occasionally mixes things up. Eventually, everything gets straightened out again. Whenever one of the other engines is feeling sad, mad, or just lonely, you can count on Percy to cheer them up again. That's why he's a Really Useful Engine.
