I purchased 2 laughing santas at the California airport 12/19/10 for my nieces. One works wonderfully, a real hit, with one niece, the other when the batteries were put in the on/off switch is flat nothing to switch on. Is there anything that can be done. One niece thinks I don't love her as much. Can I send back or get another battery pack for the santa? My niece (7years old) wanted me to write and ask. Anything very much appreciated.
