Still need to fix the blaze egg and need to add the witch egg and bat egg.

Please note that I don't know how to add this mod to Vanilla Minecraft so it hasn't been tested on that but it works on mod packs such as the packs on the Technic Launcher anf FTB Launcher, so it should work on vanilla minecraft but I can't guarantee it!
