Okay so this is supposed to be an absolutely retarded over-the-top character set in a obviously fictional setting, but I'm getting really hung up on "How is the arm gonna work when there's a loveseat built into the neck?" It's really important to me though that the loveseat is set in a way that if this little worm fella sits in it his head will pop out right where a human head would be, and his tail starts rolling where the shoulder would be, but I'm not sure how to get it right. I could go for a much more simple design like Spud the Disposable Assassin or something, but my main goal as an artist is to make really dynamic stuff, and I want the arm to have full functionality without having to like completely warp reality or something. Maybe I'm just an autist
