A ship is taking a while to reach Brendam Docks and to pass the time Thomas and Percy play "Hide and Peep", with Percy hiding. Percy is a good hider and when Thomas tires of searching for him he pretends to have found him. Percy knows Thomas is cheating and hides on the coal tipper until Thomas lies that the Fat Controller has arrived, and Percy comes out. When the ship finally docks, Thomas cannot find Percy and when he calls out that the ship has docked, Percy refuses to come out. Thomas asks Cranky for help and Cranky spies Rocky lowering Percy behind a wall. Thomas finds Percy and the two friends collect their loads on time.
Tropes featured in the episode:
