The Hotel Ducks

At the Peabody Hotel in Memphis, Tennessee, five special ducks have the most important job in the building! Every morning, they ride the elevator down from their rooftop "Duck Palace" to the lobby fountain. They walk on a long red carpet while a special "Duckmaster" leads the way. They spend the whole day swimming in the fountain and then march back to the elevator in the evening to go home for dinner! Learn more!
