A toy has a sectional, weighted body with a longitudinal slot. A grooved pulley wheel is rotatably mounted within the body in alignment with the slot, and a cord passes through the slot and under the wheel, engaging in the groove. A hook on one end of the cord adapts it for positioning in an elevated location, so that by raising or lowering the opposite extremity of the cord, the toy gravitates toward the lower end.
