According to Charles law "At constant pressure, the volume of given mass of gas is directly proportional to its temperature".
Since the pressure in the balloon is likely retain, the lowering of the temperature will reduce the volume of the gas and cause the balloon to shrink. The gas particles will lose their kinetic energy and move with less vigor.
