Mario, Carol and Lauren were called to the diary room yesterday; they were told that their task was to pretend to be held prisoner, by a fake villain called Mr Big.
To pass the task they must get the other housemates to complete a list of demands. They will be secretly living in luxury watching the others from their hidden room.
Mario pretended to be Mr Big, dressed up in the diary room, and was shown on the living room plasma, talking through a voice changer effect.
He introduced the task to the other housemates. The screen cut to static, Mario then quickly ripped off the costume, and went down to the task room to sit in one of the trick chairs that makes it look like they are tied up with Carol and Lauren in front of a dungeon backdrop. The three tied up prisoners then appeared on the screen, and to show that Mr Big was serious, he dropped horrible insects all over the housemates in the chairs. In fact this was a trick, and the insects were really harmless lentils and black beans.
From this point onwards Mario, Carol and Lauren will be based in the task room, where they will watch the others from the luxurious half of their room. When it is time for a demand to be made, they will record these demands in the diary room through a voice changer, which will then play into a pay phone in the house.
Yesterday's demands included getting the housemates to eat gruesome food and making Louie walk on glass.
But there were some positives for the other housemates, with Courtney being reunited with her husband in the small task room.
Watch the task on Channel 5 tonight from 9PM.
