Okay. Weird doodles. Something I've been meaning to draw for a week or so, a four-armed person would need a second set of chest muscles to work, something I don't think I ever see!!!! Or else the bottom arms wouldn't be able to bring themselves in front of the body! Among a bunch of other movement issues! So I tried to draw second chest muscles. I decided that means a second set of nipples (and boobs) otherwise it's way more difficult to convey. ANYWAY.
