A note on Rotten Slimeball, the kitty cat: As soon as I discovered that Daz offered a cat to download for free, I couldn’t resist taking advantage of the product. The default state of the cat character is, of course, much cuter than the deformed Rotten Slimeball. In order to make a truly supernatural feline, I elongated the legs and the neck and increased the size of the ears. It has lopsided eyes and a protruding tongue because…well, it’s a zombie. Its texture is taken from a photo of red lichen on rocks.

Will’s barf was also surprisingly hard to do. I never thought I’d have to seriously think about the physics of spitting up blood, but I just did today. I decided that it would dribble viscously, rather than spew with force.
