Thumper is a quarry machine with two arms and caterpillar treads. He is used for loosening rocks.
Thumper was brought to the quarry to help clear rock, but his arms accidentally dislodged an enormous boulder which chased Rusty, Skarloey, and Rheneas down the line before nearly crushing Percy and running into the sheds at the mine. Nowadays, Thumper is used for slate mining.
Thumper is not based upon any known quarry machine - at any rate, a machine of his type would be extremely hazardous to those around due to the lack of a window at the front of the cab, making the operator unable to see.
Thumper is painted orange with his name painted on his side of his bonnet in white.
