The Slime

The Slime is a biome that spreads indefinitely, turning every block it spreads to into slime block or slime block wall, both spreading the biome. it spreads very quickly but gets slower in hard mode. It spreads about 72 blocks an in game day (3/min). Enemies include all types of slimes (except King Slime, Rainbow Slime, and Pinky)

WIP!

There are Acid Crystals that Summon The Slimemils, a boss tower that is stationary and hasblades of slime.

You can go inside like a normal building, but it shoots Slime Ball at you. You have to mine the tower to kill the boss, and the less blocks there are, the more it shoots. there are also windmill like blades made of slime that try to stop you from getting in. Defeating the boss tower Spawns A Slime Mill randomly across the world and tonnes of Blue Slimes around you.

If the world becomes 31% Slimed then every slime block and wall becomes the block it was before and it will say:

The Slime Has Retracted! at the bottom of the screen and the slime will spawn from any slime mill that it left or player placed slime blocks.

Acid Crystals are the Slime's counterpart to; Giant Ice creams, Crimson Hearts, and Shadow orbs.
