Big Bird hears Herry Monster, Maria, Bob, The Count, and Biff making a fuss over a new baby on Sesame Street, and he feels jealous and left out, so he starts to sing "What Can the Baby Say?" He sings that the baby can't do anything; all he does is lie there and gurgle. At the end of his song, Bob talks to Big Bird about how he feels, and then lets him hold the baby. Bob tells Big Bird that the baby will need friends to teach him things while he's growing up.
