Abstract: An aerodynamic toy apparatus is mounted at one end on the side window of a motor vehicle and is manually manipulated from within the vehicle by a passenger in the back seat. A generally rectangular support member is configured at one end to be received on the window glass and has an aerodynamically shaped cup-like shroud portion at the opposed end positioned outwardly a distance from the vehicle. A retractable toy member connected to a pivot arm on the interior of the shroud is movable from a retracted position to an extended position to be acted upon by air currents as the vehicle moves and is manually manipulated by cables from the vehicle interior to simulate flying and other movements.
