The NPR logo.
NPR was a running gag on Creature Talk where the Creatures imitated NPR hosts. It could be seen/heard a lot during the 24-Hour LiveScream.
History[]
During a Creature Talk, the Creatures were discussing that the only podcast they have to pass on iTunes was NPR (National Public Radio), and because of that they all started talking like hosts of NPR talkshows. Gassy was the first to talk like an NPR host.
