There are creatures that are harder to raise than the Cow. Besides, this isn't the topic to discuss this.
With that said, It's a giant freakin' cow. That alone makes it a great creature. :p
...What was user banned for, I wonder? >_>
Anyway, this is a good skin to edit if you want to make a cow with different colored skins. The default one requires a lot of tweaking to get it to look like this.
Just putting that out there.
The detail level only affects how many layers of images are stacked on the ground and buildings, and things like clouds and rain effects, and shadows. It shouldn't affect the creature much, if at all.
You may need to update your video driver. I know that that is what I need to do with this machine, and I can't play Black and White until I do. (I use dial-up, and any sort of download is out until I get DSL! <_<) The entire system crashes if I try to load any sort of game, even a *cough*...
Actually, I have noticed that sometimes the creatures textures or whatnot do mess up in certain poses. It's not just the Zebra, and it happens quite often. It's just that unless you spend a lot of time watching your creature, it's not that noticeable, and it doesn't hurt things so I guess no one...
