Silly Billy is a fan-made Thomas and Friends Season 11 episode made by BiggestThomasFan. It would have aired in the place of "Don't Be Silly, Billy".
Sir Topham Hatt had bought a new engine from the workshop. The engine is an orange tank engine named Billy. Sir Topham Hatt asks Percy to show Billy around and how to do his work.
Percy shows Billy how to shunt trucks and get coaches ready for the big engines. Billy sees this, but has a silly idea. He shunts trucks for James' goods train at where Gordon collects the passengers for his express and shunts Gordon's express coaches to where James was to collect his goods train. The two main line engines get cross and Percy has to quickly put things right. He sorts out the mess, and Gordon and James leave with their trains now running late. Percy scolds at Billy, but Billy can't help but laugh thinking it had been funny.
The next day, Percy isn't feeling well and has to go to the works to get better. Rosie is asked to work with Billy. Billy is still acting silly, and even has a silly idea. He tells Rosie that Sir Topham Hatt wanted her to pull Gordon's express. Rosie is worried, as she's not strong enough to pull the express, but doesn't want to let Sir Topham Hatt down. So she pulls the express out of Knapford station and onto the main line.
During her journey, Rosie breaks down. Gordon is sent to rescue her. He gets the train to Wellsworth, shunts Rosie into a siding and takes the train on. Sir Topham Hatt soon arrvies to speak to Rosie. Rosie tells him what Billy said to her about pulling the express. Sir Topham Hatt then speaks severely to Billy. He punishes Billy by telling him to pull Rosie's goods train while she's being repaired and gives Billy Percy's mail run everyday for a month; and tells Billy that he will be sent away if he causes more silliness on the railway.
Billy, ashamed of himself, apologizes to Percy, Rosie and the other engines. He then starts to work hard and proved everyone that even he is a really useful engine.
