It's Louisa vs Tina as one girl takes to the gunge tank, while the other must battle her way through the gungy inflatable obstacle course, grabbing bean bags with her teeth and depositing them into the gunge pit below. At the end she must slide down into the gunge pit herself to declare victory and pull the gunge lever on her opponent. If she fails within the 5 minute timer, she will have to face the gunge tank instead.
