>>107343289i hate when people make it a depression. hell, even the 'dome' version is weird. it's supposed to be a row of hair or nubs, and they just put a bowl of potion on their head, balancing it there. I like to draw the nubs extra long as if forming something to hold the bowl, and I would be okay with someone drawing those nubs growing together into a more solid horny bowl shape, but that's IT. you can't have a depression in your head, that's where your brains go, and almost no ancient kappa drawings show that.
that said, all the other kappa on the show have that, so it's odd she doesn't. she's also much less green than they are, so we're thinking maybe she's a halfling.
