The male campmates agreed to let the women take on the challenge, with David Haye joking that "it is usually the women who do a walk of shame after a heavy night out".
Charlie said: "I was totally up for doing it. I'd no idea what it entails. It's called the Walk of Shame and I've done that once or twice before in my life but I doubt this one will be the same."
Ashley added: "I've done a few walks of shame in my life; yeah, it's happened - this will be just another addition to the book! I feel confident about us."
Charlie was in a giant star, with a smaller star hidden in each of the five points, guarded by various jungle critters.
Ashley was in a dunking tank and had to answer three questions for each star, with each correct answer giving Charlie 30 seconds to find it. She was dunked every time she answered incorrectly.
The girls managed to win four out of five stars for camp, impressing Haye, Eric Bristow and Hugo Taylor.
