For the latest shopping task, Renee, Marnie, Biggins, Samantha, James, Heavy D, Katie and Bear are humans while Aubrey, Frankie, Grant, Lewis, Saira, Chloe and Ricky are robots.
The two sides will be going head to head for the luxury shopping budget that only one side can win.
But as part of the challenge, the humans can boss the robots around and some of them are enjoying full use of the power.
Heavy D took great glee in forcing Chloe to clean his underwear, demanding she "get those skid marks out" before generally bossing her around all day.
Chloe however retaliated, first by giving Heavy's shoes a 'drink' and then by pouring ketchup and mayo all over the bed he shared with Bear.
After finding out, Heavy fumed: "That's out of order, that's vandalism.
"Whoever it is, is f**ked. I've been waiting for this, I've been waiting for a bit of drama"
Heavy initially blamed Bear but he insisted it wasn't him: "Why the f**k would I put stuff in my own bed? It's on your side, someone has personally done it to you, someone has personally f**ked you.
"It's the quiet ones you've got to watch in this house."
As Heavy got angrier, Bear told him: "You can give banter but you can't take it."
Heavy snapped: "That's not banter, I've never done anything like that. You're trying to justify that?"
Bear replied: "I'm saying you can give it but you can't take it."
But Heavy disagreed: "I've never, ever gone to anyone's bed and put stuff in their bed, that's what you do in school, we're f**king adults. Why are you trying to justify that? You're trying to justify that?"
Bear replied: "I'm saying this, let me talk, you're like a loose cannon. You can give it but you can't take it. Me being me, if someone did that to my bed, for me I'd find that funny."
Meanwhile, in the bathroom, Saira told Chloe to keep "playing it calm".
