Once upon a time, there was a brave bunny police officer, one Judy Hopps, and with the help of her trusty vulpine assistant Nick Wilde, she had saved the entire Zootopia from an evil sheep plot, and-
-And then she woke-up next to the aforementioned Wilde.
“Good morning, Jude!” the aforementioned Wilde said in an atypically high-pitched voice.
“Good morning, Wilde,” Hopps replied – in an atypically low-pitched voice that cause her to blink in confusion. “Ah, is there something wrong?”
“No, Jude, nothing is wrong,” Wilde continued, as he turned around so that his butt faced Hopps’ face… wait. Hopps bent all of her will into a single unit and focused on it, just for different reasons than the obvious…
“Uh, is there something wrong with your butt?” she asked her partner.
“No, Jude, there isn’t,” the partner replied, as he wiggled his butt, and Hopps’… member rose. She blinked.
“Uh, why am I a guy?” s/he asked no one in particular, but Wilde answered her all the same.
“Um, because? Some people are male, like you, while others are female, like me-“ s/he turned around, revealing decidedly female anatomical features.
Judy - or Jude? – opened her/his mouth to counterargue Wilde’s statement – somehow – when someone’s loud voice came from the TV; Hopps turned to look at it, and saw Gazelle the singer preforming there; only that Gazelle was built more like a buffalo – or a cow – instead; the only thing that remained vaguely similar to the old Gazelle were her horns; the rest was largely obliterated by the much bigger body mass. Bulk, if you rather would.
“Oh look, Eland is preforming again,” Nick – or Nicky? – commented brightly. “Got to give credit for her bravery to wear such clothes with her body shape…”
Somehow, this clinched it for Judy/Jude – s/he really was in a mirror universe, and s/he had no idea as to how to get back home…
