Pump

The Pump is an item found in Mario Kart Arcade GP 2 and Mario Kart Arcade GP DX, resembling F.L.U.D.D. from Super Mario Sunshine.

Mario Kart Arcade GP 2
The Pump first appears in Mario Kart Arcade GP 2. Upon being used, the item is placed on the racer's head and rotates back and forth while firing Goop at regular intervals. If a racer is struck by a shot from the Pump, they will lose speed, and their portrait will be covered in Goop for a short period of time.

Mario Kart Arcade GP DX
The Pump reappears in Mario Kart Arcade GP DX as an item. It acts as it does in Mario Kart Arcade GP 2.
