Zombie hordes

I've looked around but I can't find anything simple enough to use.
I need a plugin that
- Makes only zombies and villagers spawn
- Make massive hordes of zombies spawn often (not all the time)
- Makes zombies drop emeralds (randomly)
- Have some zombies run faster
- Have some zombies have more health
- Have some zombies do more damage

That's all I really need if any body knows if there's something I've missed that does this, not this plugin it conflicts with some of my plugins(http://dev.bukkit.org/server-mods/monster-apocalypse/).
Or if you could make one that would be great
Thanks

 

Add me on skype and I'll do it for you: skype name is kingstarwest
I'll do it tommorow if that's ok

 

My plugin Apocalyptic does everything but changing drops, and I'm sure there's many that do that.

 

I was gonna suggest your plugin to him

 

Sorry I only just checked this post
And thanks I was looking for this one I had it ages ago but lost what it was called
One thing when I used it the hordes spawned in groups far away from each other is there a way to change that ?

 

You could make the horde size bigger.

 

Thank you I downloaded it and it's perfect

 

Glad to help. It'll be updated to 1.4 soon.
