Channel and Rhian are wearing Bavarian Dirndl Dresses. They talk about the dresses while sat down. Then go to the messy sofa where mess is poured from above all over them while they talk. 
They get sweet food then gunge poured over them towards the end. They roll around on the sofa and floor to get fully covered as well as filling their heels up with mess. At the end they get washed off.
