The Sesame Street character has fun singing some catchy new songs (you and your toddler just might, too), explaining the difference between light and heavy, having a laugh over pictures and numbers, and sharing the screen with a good-natured Whoopi Goldberg and Julia Roberts. Of the various Elmo videos, this one really does have the choicest material and stands up to repeat viewings–a big plus with little ones. –Tom Keogh
