The children's show is introducing a new puppet character named Lily for special on Sunday that talks to children about poverty and hunger.
Lily is a 7-year-old who talks to viewers about insecurity over whether her family will have enough to eat. The puppet goes to a pantry for food and also volunteers there.
"Sesame Street" executive Jeanette Betancourt says the show invents new Muppets occasionally, usually to help illustrate particular social issues. Four years ago a Muppet was created for a special on military families at a time of war.
Country star Brad Paisley is host of Sunday's special, called "Growing Hope Against Hunger."
