Percy's New Whistle

"Call that a whistle? Just listen to this."

- Bert

Percy's New Whistle is an eighth season episode.

Plot
'Arry and Bert tease Percy for his weak whistle, but Percy gets revenge by scaring the two diesels by whistling behind them. Percy is happy with this prank and plays tricks on Thomas and Bertie. Thomas makes Percy promise to stop, but when Percy can't help himself and whistles, Trevor knocks a log down the hill, causing it to turn into a giant snowball that collides with Percy. Percy learns his lesson, and puts his whistle to good use to warn Thomas of a snowdrift ahead.
