A lot of people have wanted biome specific mobs, including me. I think a good start to this would be to have different skins for the different biomes.
ZOMBIES
Winter-styled: White fur-like skin
Desert: Tattered Camel skin
Milder biomes (all the others): What the zombies look like now
SPIDERS
Winter-styled: White with red eyes, instead of black with red eyes
Desert: Tan, only slightly darker than the sand.
Others: Current skin.
SKELETONS
Winter-styled: Appears to have VERY torn clothes, as if it was once a person with a fur coat many, many years ago.
Desert: Appears to have what looks like an almost completely degraded cloak.
Others: Current skin.
CREEPER
Winter-styled: White camo
Desert: Tan-ish camo
Others: Current Skin.
Nether: Wiki says that Ghast's can spawn Creepers, so how about a dark red skin to match the Netherrack?
I think desert zombies should be retextured into mummies, and snowy ones would have pale skin with brown torn clothes and remains of scarf.
Desert skeletons shall have shiny brown fried like bones with ossacionally a leather helmet.
Snowy skeletons should have cyanish edges around thier body, bit blue shade on thier bones.
Desert spiders would use deafult texture that they used in Survival test; and winter ones - dunno.
I have seem the thread on mummies, and that is pretty cool

This would be a brilliant idea, but just an fyi, the wiki isn't always true. Ghasts do NOT give birth to creepers.
I didn't think so, and the fact that the creeper in the pick was completely black made me skeptical, but I had no counter-proof so I put it in.
