Puck

Puck is a penguin from the South Pole who comes to visit the Big Blue House in the Bear in the Big Blue House episode "A Strange Bird." Like Harry the Duck, he sometimes quacks, although his quacks tend to be faster and more numerous. He has trouble adjusting to the climate of Woodland Valley and the Big Blue House, being used to much colder conditions. The puppet was originally used as one of the penguins on The Muppet Show.
