No one in the cafeteria noticed, but when Boopsie made his wish, Sarah McMillan suddenly lost her breasts, making her chest flat, then her facial features shifted slightly, becoming a bit more masculine, and her genitalia changed from female to male, as her pussy became a small penis. Everything else pretty much stayed the same, though, making her retain her overall feminine look. Sarah was still Sarah, but now "she" was a "he". Just like Boopsie, he had been born with a male name, but had changed it to Sarah at some point in his life, thinking that it fit him better, despite the reservations from his parents. He was now a swishy gay twinky fem-boi slut, just like Boopsie.
But Sarah wasn't the only one to become like that. The entire cheerleading squad became like that. So now Tiffany Sanders, Melissa Smith, Amber Levine, and Jessica Davis were all swishy gay twinky fem-boi sluts too. And as far as anyone remembered (besides Boopsie and Biff, of course), they were always like that.
