From this comment I made: I headcanon that Alphys has 3 "hair" spikes on each side of her head and if she goes into defensive mode she can move them to the front, sorta like a clamidosaurus, might make a drawing showing this vision. And here is the vision :D I have a lot of practice of drawing her... ehehehe
Art by me @cuyitaprogramadora DO NOT STEAL/TRACE/RECOLOR/USE FOR AI Character by Toby Fox yes you can steal the headcanon :3
