Tuesday evening's launch night saw John Partridge and Darren Day get sent into the small old claustrophobic box after volunteering out of the group.
Now, former EastEnders actress Danniella has joined them after Big Brother ordered another "decisive" celebrity to nominate someone to go into the box.
At first, Danniella nominated Winston McKenzie, but she soon changed her mind and nominated herself.
As the celebs gathered around the table, Danniella said: "I can't really pick anyone else to do it. I don't mind going in there, I already don't have my case."
Danniella entering the box meant that the furniture was unlocked in the bedroom, so the celebs could pick their beds and have somewhere to sleep for the night!
Earlier on launch night John and Darren decided Danniella, Christopher Maloney and Winston would not get their suitcases. John and Darren also opted to give the rest of the house luxury food while they live on rations.
