Max1232's Advanced Mobs modification for the 1.9 snapshots.

I've finally decided to publish one of my single player, vanilla friendly mod for Skeletons, Zombie's Creepers and Spiders!
There is a book that is given to you in game with information about the mobs when successfully installed.

To activate the modification, insert the commands from the link below into a command block. Activate the command block using a button 

If summoning mobs in to get advanced mob do not do it one by one, otherwise they will all be advanced. Do them all at the same time.

(To get a command block do /give @p command_block)

If you need help with command blocks please send me a message on skype, Puppetmaster1232
