Koko the Penguin stars in Panwapa. She wears pink glasses and loves badminton. She is very excitable, screaming in terror when she first meets Azibo the Monster and then running off to warn the others, and then hiding in her cottage. However she is also the first to go offer to help him build his house once she gets over her fear.
For the week of 14-21 October 2008, Koko appeared with Abby Cadabby on the Sesamestreet.org website, to mark Wild Animal Day.
