Gunpowder... Spice... And everything nice. These were the ingredients chosen to create the perfect pet creatures. But Professor HippoMaster accidentally added an extra ingredient to the concoction... Chemical X! Thus the Mutant Creatures were born! (Semi-quoted from a famous kids TV show..)

You thought the normal enderman was scary? Meet the mutant enderman
With a stunning 100 hearts, this massive arm-growing mutant has seven life threatening attack tactics:
Forced Look
Much like the normal enderman, the mutant enderman is also normally neutral unless stared at. But the second you look away from its gaze, the mutant enderman pulls you in towards it and blinds you at the same time!
That's not it. The mutant enderman gets angered if it sees you wearing a pumpkin or sometimes just randomly; and if it's angry, it'll automatically attack you!
Teleport

Don't think that the mutant enderman is just as simple as your typical enderman. When the mutant enderman teleports, it emits its ender-soul that produces a huge impact, knocking all mobs around it, while occasionally blinding them, and dealing 2 hearts of damage! Best be more careful when near this monster!
Melee Attack
Of course, if its hands are all free, the mutant enderman can use its basic melee attack with one of its four arms. Beware, because although the mutant enderman's inner arms deal 4 hearts of damage, its outer arms deal 5 hearts! Never underestimate the simplest attack!
Throwing Blocks

The enderman carries blocks? Well the mutant enderman carries up to four blocks and throws them at you! Be careful. This ranged attack deals 3-4 hearts at a direct hit, and 2 hearts as splash damage.
Clone Tactic

Thought you cornered this majestic beast? Think again!
The mutant enderman's clone attack spawns eight of the mutant enderman's endersoul minions to torment you. Along with that, the mutant enderman itself becomes disguised as one of them too, just a bit larger in size.
During this attack, the clones will randomly attack their target by dealing 0.5 hearts of melee damage, as well asteleporting randomly. Take note that in this form, the mutant enderman deals 3 hearts for each attack and heals 1 heart for each successful attack!
Better knock the real mutant enderman to break the spell automatically!
Telesmash

The mutant enderman doesn't just teleport. It teleports you too!
Watch out for its telesmash, which bends you through space and time into the air, hitting you with 3 hearts AND dealingfall damage!
That's not it! Some people get nauseous after traveling through space and time, and you do too! Try continuing your fighting after THAT!
Scream

Not many have lived to tell a tale of the scream of the mutant enderman. Although the mutant enderman still takes damage in rain, fighting it in rain will much increase its tendency to scream!
Along with delivering the voice of Death himself, the mutant enderman's scream deals 2 hearts of armor-piercing damage from its impact, and STOPPING THE RAIN if raining!
If you're lucky, you may individually avoid the scream's effects of major poisoning, lengthy weakness, crazy energy depleting (hunger), and troublesome nausea. However, if you're unlucky, this scream could kill you in seconds..
Death

Have you killed this monster? Good job! There's just one more barrier you need to get past:
When you kill the mutant enderman, its soul becomes unstable and deteriorates. But when this happens, the mutant enderman shoots out endersoul fragments that can explode within a few seconds, blasting you around and dealing some damage!
However, now you can grab that pumpkin and slap it on your head to prevent the impacts of the fragments and most of the damage.
Luckily, you'll be rewarded with eight drops of ender pearls or eye of enders.
Drop

Wait, is that it? Where's the awesome prize to this exhausting battle? Well, you have to make it!
While that mutant enderman is dying, you can actually collect endersoul fragments by right-clicking them before they explode. Right-click again while sneaking if you want to drop an endersoul fragment.
Now with some endersoul fragments following you, all you have to do is drop (not right-click) an eye of ender, andviola!
The combination of the endersoul fragments and the eye of ender transform into your very own endersoul hand, with 60 uses for each fragment originally following you!
Endersoul Hand

The endersoul hand deals 3 hearts as a melee attack, and has 240 maximum uses. It provides you with two abilities:

Right-click blocks to pick them up, and right-click again to throw them far away (or at mobs)!
Right-click while sneaking to teleport to any block within a radius of 128 blocks, as well as hitting nearby mobs from the impact! However, this ability damages the hand by four uses instead of one use.
Also, if your endersoul hand is running out of uses and you have some spare endersoul fragments, just toss out yourendersoul hand while the fragments are following you, and it'll recharge the hand again (with 60 uses each

It's risen from the ruins! It's the mutant skeleton!
This unholy creature has 75 hearts, and four bone-chilling attacks:
Ranged Attack

Just like normal skeletons, mutant skeletons shoot you with arrows too. Unfortunately, their arrows go through all bodies and can deal random effects such as poison, exhaustion, and movement slowdown. But all is not lost. If you can hit this creature right before it shoots the arrow, you may break its focus.
Melee Attack

Once you get too close to the mutant skeleton, it'll whack you far away, so it can shoot you again! This may not deal very much damage, but it'll take you a long time to get back!
Multi-Shot Attack

Too good at dodging arrows? Try dodging this! The mutant skeleton jumps into the air and fires six arrows at you!
Constrict

Wonder what that huge ribcage is used for? Squeezing the life out of you! In this attack, the mutant skeleton quicklysmashes you together with its ribs and sends you up into the air! Seems like a tight situation! (Sorry for bad pun)
Healing
Just like the mutant zombie, the mutant skeleton doesn't burn in the day. Instead, it heals one heart every five secondsat night! I'd wait for the sun to rise!
Death
Finally killed the undead abomination? Careful! When the mutant skeleton dies, it's body bursts into pieces, and gettinghit by flying bones will hurt! If you're still not dead, congratulations! You can now pick up (right-click) the pieces of your victory!

Mutant Skeleton Armor
But what do you do with these bones other than decoration and bragging? You craft some mutant skeleton armor! Make sure not to forget a piece. Every bone must be used! Although the full armor set is slightly weaker than iron, it has some special effects!

When the Mutant Skeleton Helmet is equipped, all critical midair arrow shots deal double the damage! However, there's a drawback! If you're not airborne, arrow shots will deal half the damage, and you can't get critical shot arrows! Also, 50% of the time, your arrow resources won't be depleted!

Skeleton arms are part of the crafting recipe for the Mutant Skeleton Chestplate.

The skeleton ribcage is part of the crafting recipe for the Mutant Skeleton Chestplate.

While also being the strongest mutant skeleton armor piece, when the Mutant Skeleton Chestplate is equipped, bows charge at four times the original rate!

How will you survive without strong armor? Be nimble with the Mutant Skeleton Leggings. When these are equipped, the player gains a Speed II boost! Dodge those attacks!

Kind of hard to stay airborne and use your Mutant Skeleton Chestplate ability? No problem! With the Mutant Skeleton Boots equipped, You can jump much higher, especially when sprinting!
Once you have everything equipped, you'll look something like this:

Or if you have the Animated Player Mod, like this:

Teach those skeletons who's boss!

Is that the HuLk?! Nope. It's just the mutant zombie.
This monster has 75 hearts of health! Watch out for its three devastating attacks:
Melee Attack

If you get close to it, the mutant zombie slams the ground and hits everything in front of it! Be warned. The mutant zombie's slam attack deals a range of up to 12 hearts of damage! Also, there's a 25% chance you'll become hungry(affected by hunger)!
Roar Attack

Don't this guy off, because he might just get angry and roar! When the mutant zombie roars, the impact deals half a heart to any entity nearby. But this isn't a simple attack. The mutant zombie is resurrecting zombie minions from the earth to support him! Summoning up to six zombies depending on the environment (spawns less in the day), you'd better run or break the blocks to stop zombies from spawning!
Throw Attack

Best stay as far away as possible from this beast. If he gets a hold of you, the mutant zombie will throw you up into the air, and then slam you down! This is the mutant zombie's most damaging attack, dealing fall damage, and attackdamage.
Healing
The mutant zombie isn't like a normal zombie. It does not burn in daylight, but instead, it heals one heart every five seconds at night! If I were you, I'd start running!
Death

Think you've finally killed the mutant zombie? THINK AGAIN.
If you don't completely incinerate the mutant zombie's body seven seconds after it dies, it will come back to life. It may not have full health, but it's ready to fight again! Of course, after three kills, the mutant zombie will die without burning.

You can watch the body of the mutant zombie vanish as it burns..
Hulk Hammer

Once you've finally killed the mutant zombie, it will drop a hulk hammer. This weapon has 64 uses, and it creates an attack just like the mutant zombie's melee attack! Good job not dying!

What is there to fear about the mutant creeper?What is there not to fear?
With a health of 60 hearts, the mutant creeper has five spine-chilling attack tactics:
Direct Attack
When using its direct attack, the mutant creeper swings its head at you, and hits you! Yup, that's right.
Take note that blocking with a sword will prevent you from being pushed back.
Jump Attack

Can't see the enemy? Maybe you should check the air. Beware, because by using its jump attack, the mutant creeper flies into the air, and lands by creating an explosion. Might wanna stay away from this monster.
Spawning Minions

Do you see those little creepers? That's what Professor HippoMaster's experiment was supposed to create. Well, the experiment worked! There's just one problem: they aren't helping you; they're helping the enemy. If you make the mutant creeper angry, it'll throw a maximum of four little creeper minion directly at you. Even worse, the minions are targeting you at the same time! Now would be a good time to run.
Charge Attack

Can't seem to hit the mutant creeper? You can take the chance when it uses the charged attack! The mutant creeper willfreeze and flash five times, giving you the right amount of time to inflict some damage! Be quick, because if you don't break it out of the charge by the sixth flash, the mutant creeper will gain 15 hearts of health!
Lightning Attack
However, it isn't that easy.

Each time a mutant creeper charges, there's a one out of six chance that it's actually waiting for you to get closer! And if you do, it'll summon a bolt of lightning down on itself, making it stronger! Be very cautious...
Dangerous? No? Watch out for the powered mutant.

This mutant creates bigger explosions. His minions are powered too.
Healing

Think you can give the mutant creeper a taste of its own medicine? Too bad, because the mutant creeper heals from explosions (not including explosions from other mutant creepers)! Try not to use TNT!
Death
And when you think you've finally killed this monster, something else happens:

That mutant creeper is charging up its last amount of energy! You'd better run now, because once it's done charging, you'll have to face the biggest explosion yet! THEN, the mutant creeper will finally be dead.

For killing the mutant creeper, you are rewarded with its egg!

You can right-click it to put it onto your head and carry it around. Eggs can be stacked on your head as well! This egg needs 3-5 minecraft days for it to hatch.

Of course, you can speed up the process by blowing your egg up (multiple times)! Once it does hatch, it becomes your personal...
Creeper Minion

Just like wolves and cats, your creeper minion will follow you around, unless you right-click it, making it sit. Here's a creeper minion sitting down. They won't despawn. A tamed creeper minion has a few features:
Give it TNT, and it will become continuous -- it won't die from its own explosions
If it already is continuous, its blast radius will increase by 0.2
Give it gunpowder and it'll heal 2 hearts
If at full health, it's maximum health will increase by half a heart
Creeper Stats
Can't tell how much health your minion has? Forgot whether your minion can only explode one time? Check its information with the creeper stats item:

Right-click a tamed creeper minion with this to see its info. You can even change its name!

Changing Name - click the top button and type in your new name; then click the button again to finalize it.
Blast Radius - default creeper minion blast radius is 1.0; a normal creeper's blast radius is 2.0
Creeper Shard

However, if you break the egg before it hatches, it'll occasionally drop a creeper shard. The creeper shard starts with no power, but it gains a bit of energy from each mob you hit. Once you right-click, depending on the amount of energy the shard has, it'll create an explosion, then resetting the power back to zero!
Of course there's just one drawback: every once in a while, the creeper shard must drain energy to keep working and in doing so poisons the user for about 5 seconds.
Loot
Of course, if breaking the creeper egg does not yield a creeper shard, it will drop 5 to 10 gunpowder.
Feeling lonely?
Then the mutant snow golem is the right creature for you! Just add some Chemical X to your typical snow golem, and viola! Your monster-killing snowman is created!

With it's mesmerizing fiery eyes, you'll never be bored again! The mutant snow golem has a few features:
Ground Freeze

The mutant snow golem automatically freezes every water block nearby and also creates a path of snow! This only works when it is standing on the ground.
Monster Attack

Like a normal snow golem, the mutant snow golem automatically attacks mobs, except instead, he throws huge chunks of ice which deal up to 6 hearts!
Healing

If your mutant snow golem is injured, simply throw some snowballs at it. It'll heal one heart per snowball.
Following

If you want your mutant snow golem to follow you, right-click it, and your name will appear above its head! Take note the mutant snow golem doesn't have the best vision and may take some weird paths to you.
Melting
If you manage to knock a mutant snow golem into the water (without it freezing the water), it'll deal 8 hearts of damage to the mutant snow golem.
Drop
Currently, the death of your poor companion will leave 32 to 48 snowballs, as well as its lighted pumpkin head.
Chemical X - Make Your Mutant

Itching for battle? Dying for a strong companion? Your dreams have arrived in a small bottle of Chemical X!

Throwing Chemical X onto the ground creates a skull spirit that picks one random mob nearby and infects it.

Then, (if a mutant is available), there's a 50% chance that the mob will turn into a mutant! If not, it'll kill the mob. Use wisely!

To prevent problems, you can throw Chemical X directly at an entity to infect it.
