The Old Quarry

The Old Quarry is an abandoned quarry situated somewhere on the Island. Diesel sent Percy here to pick up the Mayor as a trick, but this only resulted in Percy's fire going out when he ran into some flooded track. Diesel later tried to rescue Percy, but his generator went out due to it getting wet. The Search and Rescue team then rescued them.

It appears in the nineteenth season episode, Wild Water Rescue.
