Rachel and Frankie take their places on the swings above the tanks filled with gloopy cold gunge. Casey asks them in turn questions. eg. name 3 things beginning with the letter M within 5 seconds. If they fail to answer correctly then they get lowered into their tank to a certain level, lower and lower each time until they get to their shoulders and an over head tank releases more gunge over them and they must dunk their head into the gunge. If the answer correctly their opponent goes down.
Includes wash off.
