When industrialization boomed, so did the global demand for oil. Thus was born the nodding donkey, an invention that automated the oil extraction process for better efficiency. ROKR replicates this tall machine for its Industrial City Series with an impressive depiction of a steam-powered pumpjack all set to harvest tons of liquid gold from underground. It stands at 243mm (or about 9.5 inches) tall and uses a coordinated gear train to activate the piston pump that powers its cantilever's rhythmic motion. This standout piece can be activated in sync with other Industrial City models through its wireless receiver or its rail-type power base hub. Collect them all today!
