Added Mobs:

Black Plodder, a spider-like creature that is a nightmare in the dark, drops Chitin, Chitin can be cooked, and made into a wood-like blocks (stairs, buttons, fences, etc), tries to break torches, and scared of White Raptors.
Yellow Meeper, a creeper-like creature that is a friendly livestock animal, drops Meeper Meat, it can be cooked, also afraid of Red Cows for no reason, can also breed.
Bluvg, a insanely fast villager-like creature that is neutral, drops lapis, can also breed.
White Raptor, a hostile chicken shaped robot that can only be harmed by melee attacks, drops iron nuggets, kinda funny looking.
Red Cow, a friendly cow that is red, more breeding items like Beets and Redstone.
Purple Charzo, a neutral ocelot-like creature, can be tamed with amethyst, follows motionless players that hold amethyst. When Tamed, they will attack any creature that harms you.
Green Seeker, suggested alexandru20111, it quickly shoots sludge at enemies, it flies, and drops slime and emeralds, found in caves in the Green Dimension.
Green Scrapper, similar to the Seeker, but it does melee attacks, and drops scutes instead of slime, also found in Green Dimension caves.

I recommend using JEI for recipes, or look at the images.

Thanks to alexandru20111 for the idea of Toxic Sludge and Seekers!

Feel free to use it in any modpacks or videos!
