Nibbenator's Mutant Mobs

Something's off. Kill the undead and take the mutations to create biological weapons of war, along with surviving the very few overworld anomalies that have migrated from the dimension into the overworld.

About this Mod

It's a mod that adds more mobs. Some mobs spawn in one of the two dimensions and some mobs are craftable. There also may be some more specific ways to spawn some mobs other than crafting,(Hint : Chop down a bunch of logs or leaves (at least 500 times) and then get attacked by a certain cricket that spawns in the overworld.)

To spawn some of the mobs, you may need mutations, which can be dropped by any undead mob, however, it is a 2% chance.

This is what a mutation looks like.

ohhh real scary totally

This is the Kidnapper Cricket, the certain cricket mentioned in the hint. It's supposed to have a low chance of spawning, and if it attacks you, will deal 5 damage, however, if you do not die from this, you will be teleported into a different dimension that is quite hostile. I will not mention the method of escape, for that is for you to find out.

stupid bugs

And these are Antherons (mainly workers being showed in the image), one of the craftable mobs you could make. They spawn from a birther, who eats grass to produce baby Antherons that also eat grass to grow up. After the birther gives birth a certain amount of times, she will evolve into a different form that may be a bit more hostile, but unable to eat grass again.

what is that?

This is the alternate method of getting into the dimension, it is called Reservative Essence. You make a portal like a nether portal, but this time, out of bone blocks, and then power it using the Reservative Essence. Unfortunately however, you may need to go into the dimension to gather resources to craft this item, which makes it an alernative of getting in that can only be obtained by getting in.

There is so much more contained in this modification but I do not want to spoil too much of it in this description, as I would want you to see it blind without quite knowing everything.
