It was time for the annual Sodor Pie festival. Percy enjoys the smells of the pies as he goes by the factory every day. But this year, Sir Topham Hatt has chosen him to take the train of pies to the festival.
"Percy, you are to take the pies to the festival." Sir Topham Hatt told him. Percy was pleasantly surprised. He thought that a strong engine like Arthur or Henry would take the train. "The pies are waiting down at Edward's station. Go and get them, then take them off to Maithwate where the festivaties are being held." he told Percy. Percy then puffed off to collect them.
He arrived at Edward's station. The pies were loaded into small vans and Percy buffered onto them. He waited until the line was clear, then puffed chipperly off to Maithwate.
The people cheered when he arrived with the vans. He left them on the siding and went to get a drink. But while his tanks were getting re-filled, a man walked up to him. "We need more pies!" he said to Percy "Please go back to the station and get more!" Percy was glad that he was going to be working hard.
He collected the vans from Murdoch and puffed back to the festival. But then there was some trouble. Emily had taken some passengers to the festival and left, but the signalman had accidentally switched the points back to the siding where the pie train was. Percy was heading for trouble.
He saw the station come into view. "Hello!" he said as he whistled to some children. Then he saw the siding. He thought nothing of it until he saw the trucks! "Oh no!" he cried. His driver quickly threw on the brakes and then jumped!
Percy hit the train of vans with a loud crash. Some wood went into the field and pie went onto the station platform and the tracks. Two of the vans were destroyed, nut the others were just derailed. Later Harvey came to pull him out.
Percy felt silly. He saw the mess he had made and thought he had ruined the festival. His driver thought differently, though. "Percy!" he said to the messy, green engine. "Yes." Percy responded quietly. "Look at yourself!" he said as he pulled out a small mirror. Percy looked at himself. He was covered in jam, some pie crust, and lots of blueberries and strawberries! "Bust my buffers!" he said in surprise.
Later he was cleaned up and the festivals resumed. But before that, they took a picture of him in his pie mess. Now his driver keeps the picture on a shelf in the shed. Percy hopes it will never happen again, but he likes pie so much that it won't bother him one bit!
