It's Katherine vs one of her best mates, Danielle on The Plunga! Katherine starts on the ramp and must answer questions. Everytime she gets a question incorrect, the chair will rise to the next level. If the chair gets to the top of the ramp, then Danielle gets to plunge her. However, if she answers all of the questions on the card before the chair reaches the top, then she gets to swap with Danielle, and Danielle will be immediately plunged!
