Wearing pink Speedos, Marc has to answer 3 questions to try and shorten the length of the word he needs to work out from the clue and the letter sunk in to the swamp. Each time he gets a question wrong he's pied. With 1 correct answer, he gets in to the swamp with a 7 letter word. As he slops around in the swamp, clay is scooped up and poured over him to make sure he's nicely covered.
