The Endergetic Expansion

The Endergetic Expansion is a worldgen mod created by Endergized, pengu61151, minecraftabnormals, and cipherzerox that adds new biomes, new mobs, and other additions to The End. It also new blocks, plants, food and bosses to the game.

It aims to expand The End, a barren world, into an alien world filled with structures to loot, better landscape and add alien flora and fauna.

This mod was originally created for ModJam 5 and called Endthereal, introducing the Eetle (unrelated to Eetles Reborn). Biomes and creatures have been inspired and created on the Reddit forum Minecraft Abnormals. It has also inspired other Mobjam mods like Stygian End in Spooky Jam 2018
