The Propeller Leg is a feet part that the Ridepod can equip. Its in-game description reads : "Spins round and round and lifts you into the air." The Propeller Leg is one of the most advanced feet for Steve, as it is much faster than the Roller Foot or Multi Feet. It proves to be very useful for beating Time Attack medals if you have some good weapons for the Ridepod. The Propeller Leg can be bought in Chapter 5, or it can be made one Chapter earlier.
