Jasmine (Jeff turned slave girl) did the belly dance she was asked to do with more gusto than he thought he could muster. When the dance was finished she was congratulated for her entertainment and asked where she learned how to do that. Jasmine politely fended off the praise of her peers and questions about where she came from and who she knows here, as nobody realizes its Jeff.
Jasmine got away from the crowd she had summoned and noticed a small group of teens huddled by the fence, drinking, chatting and laughing, but when she blinked, she must have been mistaken because there were a group of 80 to 90 year olds dozing on lawn chairs. undoubtedly the (great?)grandparents roped into chaperoning.
Jasmine continued enjoying the party but had to halt suddenly when a small horde of 6 or 7 year olds came running through screaming and being a general nuisance. Jeff wanted to find Emma, who had disappeared while the belly dance was going on. He thought this was supposed to be a teen party. Maybe younger siblings...
He felt uneasy being unable to say no, and even more so having his gender swapped without his consent and forced to parade around. He wanted to avoid people but much of those around her a moment ago had disappeared. Looking around Jasmine noticed a group of possum feasting on half full plates of food that were on the ground, a few people idly chatting, and some squirrels scampering over a frisbee... Jeff's brain was trying to tell him this is normal but something about it felt off... Jasmine sauntered up to Tom and held back her revolting disgust, his face was covered in acne and though he was a sweet guy, no female could stomach to be around or look at him.
All the girls agree, and Jasmine remembers discussing how disgusting he is in the girls bathroom. Jeff realized he had never been gossiping in the girls restroom. "Tom, do you know where Emma went?" Despite realizing someone is messing with the party goers and reality. looking at Tom's face ooze with festering zits was super nauseating, even though Jeff loved a good pimple popping video. "I think she went inside. Oh, and nice dance Jasmine." "Thank you!" Jeff nearly vomited, something is definitely up with reality.
Jeff wanted to tell Emma they should leave, but there's the issue of finding her, and then with getting Jasmine to communicate directly enough to realize something seems wrong, and then to get away safely...
