Verity slightly cheated on the Escape Room (using her bum and feet) so is punished by cleaning the studio. She cleans the gunge tank only for it to empty over her and her cleaning uniform. So, she is sent to clean the escape room shell where a pipe can suck up all the old gunge. However after trying to unblock the pipe, it goes into reverse and drenches her in months of old gunge. She then sits exhausted and covered in slime wondering how to unlock the cage. Is it the big red button?
