To stay clean our contestant must guess the safeword that connects to 4 other word clues. For example: Cheese, Tomato, Crust and Dough would be the clues for the safeword pizza.

they have 4 minutes to collect 20 safewords otherwise the gunge is released.

mattuk wears the full West Ham home football kit with socks and sits in the gunge tank. As the counter moves towards zero, he starts to struggle to correctly name the safewords and ultimately ends up covered in thick yellow and blue gunge.
