Arlight, I fixed the dithering issue, while adding some other cool things.
dunno why you used a preview since the size of the full piece is less than 100x100. also the dithering works against the smooth texture of slime, if you want transitions, you've got room for more colors :P
It looks perfectly nasty. You could probably go the extra mile and remove the dithering, though.
"Its elastic type slime allows it to suction its self to walls and various objects." Like your face! Anyway I really like it good luck!
much improved
