Yet another of my weird spore creatures. I have only been able to upload some of my newer works, because unfortunately my stupid computer likes to deny access to my better critters
Put two arms on the back where you want the tail to be, move it to the position you like, so that they sit on both side of the body, then delete the second arm by clicking 'a' on it and dragging it away.It's hard to explain... Just play around with asymmetry tool until you figure out how to do it in a way you like. That's what I did
