This is like twister in a way -- the mat has the letters (in alphabetical order) around the outside, and the object is for the child to put different body parts on the right letters (selected from the "tornado" spinner).  There are 5 letters or free spaces each time -- feet, hands, and ear.  It doesn't specify which hand, which is good.  The kids will be twisted up trying to get their ear on the "m" and hands on the "a" and "b"!  Mat is a thick, sturdy plastic, adults and children have played on it with no issues.
