Mattel's plush Sing-a-ma-jigs have become this year's must-haves for the little ones. The eerie-toned talking and singing dolls each belt out a different note when their stomachs are pressed. Play them alone or grouped together for synchronized harmony. Navigate between chatter and crooning by pressing the left hand and then press the stomach to activate a motorized mouth that moves as you control its sound. Battery operated, for ages three and up.
