I have a lot of Grand kids. But two of them are a boy and a girl. He has Autisim and is the sweetest boy ever. His sister is the greatest and is his best friend. So I got them this great set of two Magic Snake Twist Puzzles. They love them. They work together to make different shapes and it's great becuase it keeps his mind focused on one task. Plus they are having a lot of fun doing it! Really great Puzzle Toys!
