I like to think that some skeletons can't change their ectobody unless they have hormones (lyra being one of them)

It’s been ten years and I still don’t understand the appeal of ectobody. Especially the skeletiddies variants. Probably for the same reason that I don’t understand the appeal of “human-version” monster characters. I’m too much of a creature for this. -*gently bites at an exposed rib bone*- uwu

It's so important to me that Lust always has a rockin' rack. Even in his masc ectobody, he deserves only the best set of pecs.

Hear me out: while most skeletons can freely summon either ectobody, some skeleton's magic has a disability to make ectobodys they were "born" with. :)))) make it where Razz has that magic disability and he tries really hard to form a fem body, only for his magic to spark and practically shut off.

Would it be an unpopular opinion if I said that I always kind of preferred when people draw him with a huge ass without the ectobody stuff? Like, just a blatant violation of how a skeleton would look?

Text: "Don't forget to draw for pleasure, too!", with a cropped artwork of Killer Sans with an unsettling / deranged expression on his face, with black tar overflowing from his eyes. Artwork cropped to zoom in on Killer's shirtless ectobody, man-tits out along with a heavily lined bulge for his shorts LMAO The same image as the second photo, with a salute emoji toward the bottom right.

I so need to make an oc with yellow ectobody

Recently I have an obsession with it.
And I keep searching for Dream.

Idk if the obsession is for Dream, yellow ectobody or simply Dream naked—
