It's hard to tell how Unnerving the magical entities are because Tiffany and Candace were raised by them but like look how they move is Not Normal
Winter: at first you simply think he's too still and moves too slow. But then one day you're on opposite ends of a field and you fall because you step in rabbit hole, and when you look up he's already there asking if you're all right. You do not know how he got there
Amadeus: it isn't so much how they move per se, but how they don't. They're the most human looking and it just makes the general lack of breathing and blinking worse. You think that's the worst of it though, until one day you call them and they turn around without moving
Magma: this one moves too fast and too often and his body won't just stay in one shape. You know he can see, but you can't find his eyes to save your life, so you never know where he's looking or planning to scuttle next. If you get too close to him, you could be hospitalized with third degree burns. You hope he never bumps into you and try to keep your distance without being rude. You're pretty sure he notices
Forest: you do not know how long is limbs are supposed to be. You doubt he does either. They stretch and contract according to whatever's convenient. His eyes never blink at the same time, and it's somehow worse than all the others who don't blink. Whenever he so much as twitches, his body crackles. You half expect his head to fall off as he turns it. At least he'll never be able to sneak up on you
