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.

GlasgowGunger looks like he's off on his summer holidays rather than a trip to the gunge tank in our very first episode. As the counter moves towards zero, he starts to struggle to correctly name the safewords and ultimately ends up covered in thick red gunge.
