Despite falling asleep in record time, you don't sleep too well, waking up a few times - obviously yesterday's events still stuck with you.
As a result, you're not surprised that you're not exactly well rested the next day despite sleeping in, and slowly get up to start your daily routine - or at least the parts that easily translate to being a fox who's also currently unable to completely remove her clothes, so no showering or bathing, and you'll probably have to re-learn how to brush your teeth if you don't manage to change yourself back before the fair moves on.
Breakfast comes first though, and even just having your usual quick meal makes you much more alert, and while you finish up the rest of it, you remember the "questionnaire" you got yesterday and quickly fill in everything.
Most of it was roughly what you'd expect to see in a hospital, or as part of a mental assessment, but one asked you to inspect yourself for any irregularities, and while you do so, you notice that your clothes seemed to have shrunken slightly - your shirt now barely exposes your belly button - or at least the fur in top of it - and your pants no longer go past your ankles.
You note that down, finishing your observations and ready yourself to leave for the carnival again, but it takes you until you reach the elevator to figure out that your clothes are still the same size as before, and instead it was you who grew a few inches!
Also, while the fact that your lack of control or understanding of the power you demonstrated yesterday is probably to blame for these uncontrolled changes, the only thing you feel about this change is excitement, both because this means you could maybe change yourself further, and because that slight change somehow made you feel more confident and secure once you realized what happened.
Admittedly, it does feel rather nice realizing that a decent part of the population now needs to look up at you to see your face, so you make your way back to the laser tag arena you've spent most of your time at yesterday with a new spring in your step, and while you arrive much earlier in the day than yesterday, word apparently got around about the carnival, because there are nearly as many people visiting as you noticed yesterday when you went for food.
Maybe they just weren't done setting up yesterday though - you're pretty sure that the big stage you passed on the way to the arena wasn't there yesterday, and more attractions means more interested people checking them out, right?
As you arrive at your destination and enter the lobby again, one of the security people waves you over almost immediately, gestures at the "Employees only" door you know pretty well by now, and gives you directions to a different room than the one you've been to previously.
You follow the new directions, and arrive at a slightly bigger door leading to a large, mostly empty room that might've been a large garage before most of the walls and parts of the ceiling got covered in both sensors and other technological doohickeys.
You also spot Roy and Dave across the room, the former still a mouse, and practically vibrating with excitement while he points several sensors at the clothes you left behind yesterday, whereas the latter looks even more tired and weary than usual - even as he sees you, he only nods in your direction, opting to stay silent until you are closer.
"You know what, I take everything back I said about this being an easy job yesterday - screw you for being so hard to transform, I spent most of my waking time getting everything in here set up for Mister Hyperactive over there."
He sighs, "At least I can take a break now and watch you get zapped for science or something - hey, Roy! Your subject's back!"
The mouse jumps in surprise before turning to you and Dave, "Oh - fantastic! I can already tell you've experienced a few more changes - aside from your increase in size, you also seem a bit rougher around the edges this time, but first things first - did you answer my questions?"
You hand the torn notebook page back over to him after quickly correcting your misconception about your clothes shrinking, and he wastes no time reading through it all.
He then asks whether anything notable happened yesterday or today, and you retell how you got jumped, defended yourself, accidentally caused another transformation, and how you not only felt extremely drained afterwards, but also how some of that feeling still remains today.
Roy adopts a thoughtful pose, rubbing his whiskers absentmindedly, and you're pretty sure he's already coming up with new experiments and hypotheses to test, but all he has to say on that topic was "Interesting..." before he looks back at you and rubs his paws together: "Alright, we have a great setup here, and lots of ideas to try out, so let's get the experiments underway!"
