Children absorb and learn values and behaviors from many sources as they enter into the larger world.  This delightful adventure teaches Elmo the importance of sharing, community, cooperation, and friendships.  He navigates his way through scary and unfamiliar territory gathering a cohort of new friends who overcome a selfish person.  Because the content might frighten some children, Bert and Ernie occasionally interrupt the action to talk about possible fears.  I began watching this story with my nephew when he was not quite three.  It remained his favorite for several years.  Familiarity with Sesame Street, although not essential, is helpful.
