Siani and Rhianna are back and playing Don't Laugh or You'll Lose. The loser will be stripping naked and going in the gunge tank. Siani is still a gunge virgin and Rhianna has never been in a tank before so wither way we are going to have a first! Ivy is hosting and gives Rhianna two minutes to make Siani laugh. If Siani laughs within the two minutes then she will be getting naked and gunged for the first time however if she can keep a steely face throughout two minutes then it is Rhianna who will be stripping off and taking a seat in the tank. It's fiercely competitive, Siani is determined and Rhianna tries funny faces, tickling and terrible jokes to try and force Siani to giggle. She certainly succeeded in making Ivy laugh but who ended up in the tank and covered in pink gunge? Don't look below if you don't want to know!
