A quick fire game means Danielle will take her seat on The Plunga! and Katherine will take her seat inside The Gunge Tank. As Danielle is on the Plunga! ramp, she will have to answer the questions. Everytime she gets a question wrong she will move up the ramp. If she gets to the top, she has lost and will be Plunged into the 3,000 litre gunk pit below. If she answers 2 questions correctly (even if she still gets plunged) she will get to pull the lever on Katherine when she gets to the top. Things could get very messy here today!
