In a test of their natural talents, the housemates must take part in that holiday camp favourite, a Knobbly Knees Contest. Each housemate must take it in turns to take to the stage and stand behind the Knobbly Knees Box, parading their knobbly knees. One housemate must operate the Knobble-o-meter. Remaining housemates must judge how knobbly a housemate's knees are by cheering for their knobbly knees performance. The louder housemates cheer, the higher the Knobble-o-meter must go. Once all housemates have completed their knobbly knees performance, housemates must collectively decide which two Housemates - one male and one female - have the knobbliest knees. These housemates will be officially crowned winners of the Knobbly Knees Contest and will receive a special reward.

Oooo... and you may be wondering what this special prize is? Well i believe it has something to do with a secret house :P
