Caitlyn takes on Brook on The Plunga! Caitlyn is on the hot seat waiting to answer the questions, each time she gets a question wrong she moved a notch up the ramp, if she gets to the top, Brook gets to pull the lever and plunge her into the gunge. If she wins, she will swap places with Brook and get to gunge Brook instead. Whoever ends up in will have to complete a number of mucky challenges.
