The original I put together was larger: , but i ended up scalling it down to the following framework: Here's a test of it with color (non shaded.. just a test). The eyeballs wouldn't be a solid color once complete, and will appear very glassy and maybe a bit larger for the two fore and two side eyes.
There's not a whole lot of safe areas that large wide sprites can fit through without clipping issues... so this thing would work best as a deep cave boss or one that's in a boss's arena (such as an deep pit in the woods that's difficult to get to without certain requirements being met).
