Junior was called by Mr. Conductor to go to Sodor to help find the source of the gold dust. Junior was almost out of gold dust himself, and so he brought Lily to help him. When they reached the windmill he took a ride on it when no one was looking, but the wind was too strong and he was flung onto Diesel 10, losing his beach bag in the process. Diesel 10 took him to the scrapyards and flung him onto James. In the nick of time, Junior teleported himself and James to safety using the last of the gold dust.
