One other thing, If you are trying to download said mod then click, Minecraft Mods in the uper right hand corner, Minecraft Comes Alive, then MCA | Downloads.

This mod adds in over 500 skins so you wont be seeing to of the same often and adds in a whole new aspect to the game:D
You can now talk, make jokes, and even get married if they like you enough 
You can even have children!
