(another module by me(Vilder50))
The Module:
this module adds 8 new "Monsters"
this module needs the "Extra Monster Spawn (Base Module) to work":
http://gamemode4.wikia.com/wiki/Thread:7484
you can read how the monsters were spawning in version 1.1 longer down
The New "Monsters":
Ghost:
a Ghost
the ghost is a invisible zombie wich looks like a ghost...
it has slowness so its not so fast and it does no damage (but it still knock backs you) and you cannot kill it.
will despawn after one minute if there is no players close to it
Dead Miner:
4 Dead Miners (and 3 in the background)
the Dead Miner is a zombie wich has a pickaxe and a golden helmet
it can mine stone(all the types of stone) (it will the way it looks)
when killed will it drop 0-3 iron and maybe its helmet or pickaxe
Wisp:

a Wisp
the wisp is a invisible bat wich has some cool particles
it will give you weakness and make your hearts black if you get close to it. (the weakness makes you unable to kill anything)
Cloud:

a Cloud
the clouds cant move... and when you get close to one will you get the poison effect and will really not be able to see anything because there is particles in your face...
will despawn after one minute if there is no players close to it
Vampire:
two Vampires
a vampire is a skeleton wich has really much speed and has a black leather chestplate
it will drop 0-1 ghast tear and 0-3 redstone dust
Void:

4 Voids?
it will drop 0-1 ender pearls and 0-3 eye of ender
Suicide Chicken:
two Suicide Chickens
(my faverite mob =) )
a suicide chicken is a splash potion riding a invisible baby zombie wich is riding a chicken...
the chicken will run after you but it wont do any damage (it wont even punch you)... the thing about this monster is that if you kill the baby zombie will the splash potion fall and kill you =D
Freeze:
a Freeze (the creeper riding a spider)
a freeze is a creeper riding a invisible spider wich makes cool particles...
when you get close to a freeze will it give you alot of slowness so you will not really be able to move (only if you jump)
it will drop 0-1 ice and 0-1 packed ice
One Click:
this module needs the base module: "Extra Monster Spawn (Base Module)":
http://gamemode4.wikia.com/wiki/Thread:7484
Extra Monsters 2.0 module
version 2.0 wich needs the base module:

the 1.1 module
the 1.1 version wich doesnt need the base module:
how monsters spawns in the 1.1 version...
the way the 8 new "monsters" will spawn: when a creeper , a skeleton or a zombie spawns will it get a random score from 1-16, and a random player gets a score of 1 then it executes from that player and finds the closest mob with a score between 1-8 and makes the monster into one of the new "monsters"
2.0 change log:
splitted the module into two modules: "Extra Monsters" and "Extra Monster Spawn (Base Module)"
changed how mob spawning works (again) (this is a change for "Extra Monster Spawn (Base Module)", but i think i should say it here...)
clouds will now despawn the same way as ghosts does
made it so if you kill the chicken/zombie in the suicide chicken will it also kill the other mob
also did that ^ for freeze
1.1 change log:
the new monsters will now no longer spawn as much as they did (and some monsters got more rare i think)
wisp and cloud now have particles on force
ghost will now despawn after 1 minute but if the player gets close to it will the timer stop counting up to 1 minute
vampire, void, suicide chicken and cloud no longer drops bone/rotten flesh/arrows/gunpowder =) (but only when killed by a player)
the module should now work better in multiplayer...
suicide chickens potion can now also kill undead mobs
