Sunshine was the topic of conversation for some of the group, who praised her as ''so intelligent'', ''interesting'' and ''truly bonkers''.
Sunshine has been branded "truly bonkers" by Ben.
The medical student was the subject of a conversation between Corin, John James and the writer-and-broadcaster after Steve's birthday party, with the housemates enthusing about her eccentricity.
Ben said: "She's just mad. She's truly bonkers. Absolutely off her rocker. And that's not criticism - it's fact. She's also interesting."
Corin added: "She is. She's so, so intelligent, that girl. She speaks so much sense. She makes me want to go home and read some books. She knows everything... She's got a really good brain."
John James later told the group that "everything she does is interesting."
Although the housemates were showing praise on Sunshine, earlier in the day the pretty vegan was left upset after some of the group, including Dave and John James, teased her for getting "special treatment" from Big Brother because of the food she receives.
After Mario came across her lying alone in the bedroom, the pair retreated to the wardrobe for a chat.
Upset Sunshine told him: "Everyone keeps telling me that I get treated better than everyone else. I'm just asking for vegan alternatives to what everyone else is eating.
"I don't want to whinge and moan about it. I'm Sunshine, I'm happy."
After coming out of the wardrobe, Mario said that he would speak to John James to try and smooth things over.
Shortly afterwards, Dave met Sunshine in the kitchen and said: "I'm so sorry. I was only playing with you."
