Hello, you are probably wondering how do I use these fancy files?
Well, it's acctually very easy to do!

You will need: Common Sense, WinRAR, 7Zip (or some other Zip file editors) and Minecraft.

1. Simply rename the file by right clicking on the one you want.

2. Then make sure the file, after you have edited it, looks similar to this: "creeper[Number].png ([Number] is the number that comes at the end of each texture file).

3. Then move the renamed file into the "mobs" folder, paste it in, and then start up Minecraft to see if it works :)

Enjoy, this applies for all the extra Mobs! :)
