What About the Big Yellow Chicken?

Obviously my children did not watch enough "Sesame Street" during their formative years. Caitlin was doing a maze in a Sesame Street writing skills tablet during homework time today. She turned to me and said "Hey Mom, am I suppose to get this big yellow chicken from here to there?" Big yellow chicken? She knows who Elmo and Oscar the Grouch are, but Big Bird has apparently not made much of an impression.
