Cool tf idea:
You have a larger, stronger animal form, and it’s a little embarrassing… unfortunately, this transformation isn’t triggered by the full moon, because that would just be too easy for you.
Instead, it surfaces a little at a time, every time you have to physically exert yourself. Lifting heavy things, running quickly, anything that tires you out, it all causes you to change just a little.
Your body automatically (and “conveniently”) provides the strength you need… involuntarily… whenever it sees fit. And the changes take their sweet time wearing off, too…
Over time, your body gets “better” at it. Struggling to hear something? There go your ears, nice and big and sensitive for you. About to lose your balance? Now you’ve got a tail! It’s getting harder and harder to hide it… but at least it won’t be hard to show people once you finally have to explain yourself.
