Party Poppers were stuffed down Thomas' funnel, and Thomas Looked sternly at bill and ben as they laughed 2. Gordon's whistle makes a farting noise because Bill and Ben put an egg in his whistle as Gordon moaned "Oh, the Indignity" 3. When Stanley backs down to his train, he runs over a fog detonator before touching his trucks as Bill, Ben, and the troublesome Trucks laugh away 4. When Rosie collects some trucks from a shed, Bill and Ben scare the daylights out of her when they jump out of the shed, and Rosie looks annoyed. 5. When James cruses under the coal hopper, Bill and Ben dump the coal over James as he moans over his red paint. 6. When Rebecca goes under the water tower, bill and ben turn it on and Rebecca gets splashed, and is the only one who laughs with Bill and Ben. 7. Topping it off is when Sir Topham Hatt gets word of Bill and Ben's pranks, then notices a box for him. but when he opens it, a pie splats in his face, and grumbles as Bill and Ben laugh their way out of Knapford Station.
