Biff decided not to justify Jon's question with an answer. Clearly the changes had gotten to Jon's head, which meant that the rest of them would likely follow suit.
Biff looked around, looking for any further changes among the four. Walter's skin was now now feminine like Jon and Biff's, and had now darkened to a creamy brown color. His eyes were changing as well, becoming more slanted. Glancing at Nadine, Biff could see she was adopting some of the same features as well. The girl's chest was now almost completely flat, and she was beginning to take on some of the muscular tone Biff had just lost.
Then he looked back at Jon. Jon was still changing, and from his girlish giggling he was enjoying the alterations more and more. His breasts where still swelling, Now C-cups, the sling bikini only covering a small stretch of the expanding bosom. His was still growing, and Biff thought he saw the color begin to change slightly at the roots as well.
And then Biff turned attention to himself. His once burly physique was now svelte and slender, and to his dismay Biff realized he was looking increasingly fitting in his swimwear. He also realized that his genitals had shrank even more, so much so that they were mostly concealed by the tiny strap of the bikini's g string.
"Alright, no one panic, we just need to stay calm, and try to work this out," Biff said, more to himself than anyone else.
"Like, work out? This isn't a gym, silly, it's a pool! We're supposed to swim!" Jon said, turning back towards the pool.
The other three jumped to stop him, including Walter, who in his haste to prevent Jon from entering the water, something all three of them felt would have dire consequences, forgot his duty and abandoned the lounge chair.
