I would turn into some sort of mutant flying land fish thing. Being able to breathe underwater and perhaps not having to worry about being crushed by the pressure as easily? Cool. Being able to fly, not having to be in a machine like an airplane, where you can soar above the clouds free as a . . . well, bird, not having to worry about engine failure or something? Completely epic. All while being able to stay on land at any given time, doing whatever you wish in the wondrous habitats spread across our planet? That's nice.
Something like that.
BTW, I think you spelled leopard wrong, Miss Doronjo. lol
