That concert the mice talked about sounded interesting, and you absolutely want to check out a few more attractions, but you decide to do the sensible thing and go back to see if Dave and Roy fixed things enough for you to get your new measurements taken yet, because you're willing to bet that you'd get hit by some transformation effect and spoil the data otherwise.
However, they're still very busy once you come back, and judging by the halfway dismantled setup, it'll take a while still.
You do try to get their attention though, as you have a few questions.
"Hey, I'm guessing you'll be busy for most of today now, right? Well, I'd like to check out a few more things here, but you said absorbing transformations messes with your data, could I get some rough measurements done before that, or at least something that'd help prevent that from happening for now?"
Roy looks up at you from his current project, which seems to involve a lot of wires and not much else so far. "Well, we should have enough sensors working still to get some basic readings done, but sadly there isn't anything that works with the many different ways a transformation can be induced, even if we limit it to just what's available at this carnival. In fact, your current condition seems to be the closest thing to a general transformation immunity, and you still experience minor, and can induce major ones regardless.
Come to think of it, depending on the level of your resistances, you might be a shoo-in for handling, or even disposing of transformation-based hazards - we should probably try to find out if it's feasible to deliberately induce your condition in someone if that's the case..."
He starts scribbling something down, while Dave looks at you exasperatedly. "Congratulations, you just signed both of us up for more work - at least I know how to do the basic stuff by now, so go stand over there and get ready for another checkup."
You go where he indicated, and not too long afterward, Dave starts taking some of your basic measurements like height and weight, while Roy joins in with the more esoteric ones after he's done jotting down notes.
Aside from your obvious change in height, everyone's rather surprised to learn that your weight didn't change as much as you would expect, which is probably why you you felt less graceful after your changes - your proportions stayed the same, so you must've gotten denser in some way.
Interestingly enough, some very rudimentary measurements of your stored energy levels show numbers that also seem to roughly match with your reduction in weight rather than height, and with the intensity of the blast you've emitted earlier as well.
You briefly wonder why that might be the case, but Roy has a valid objection to drawing any conclusions yet - this was a single, uncontrolled incident, it might've just been a coincidence.
Either way, you now are done with anything useful you can do here, and unlike last time, Roy is actually okay with you exposing yourself to transformation vectors again, even if he'd prefer for things to stay the same until he can fix his precision instruments and take proper readings again.
