some take sliders vaguely correlated with human attraction and slide them up really really high, past the superhuman range and just keep going. cheekbones high enough to be horns, giraffe-necks, bug-eyes, stuff like that
some make the reasonable inference that humans probably have repeated body parts folded into four dimensions that they hotswap and do the same for their human forms and just have too many arms and fingers and eyes and stuff that keep flickering
some have strange aesthetic preferences by human standards that they incorporate into their human forms. tetraspace likes ribbons, so a tetraspace might decide to have two mouths with six tongues each about a meter long trailing behind them, stuff like that.
of the remainder,
some just don't get humans quite right. facial features are off, "close enough" by their standards but not by ours. arms and fingers the wrong length. garments don't actually make sense as clothes if you pay attention.
top 50% or so of tetraspaces (who try to look like humans) have no problems w/ this. they just look like glowy floaty humans
so the reason tetraspaces adopt human forms is to communicate with humans. "their" "goal" is to find the strongest million or so humans, implant them with tetraspace eggs, they fight to the death, the ~1% who survive get to be the new tetraspaces, repeat
now that ive been reading twig and also replaying hello charlotte and also just thinking more about the logical consequences of the setting obviously there should be body horror tetraspaces
