I saw several of these in the shop where I buy my supplies and I could not resist making one myself.
For those who don't play Minecraft - the cave spiders are a nasty variety of the normal ones, that can only be found in abandoned mineshafts deep underground. They can kill a player very quickly thanks to their venom.
Ok so MAAAAYBE it does not have glowing red eyes really, but I'll see what I can do about it - and yes I know cave spiders are not greenish, but I could not find blue-tinted ahem...body parts, nor black for that matter. Maybe I will have more luck next time.
