This is a small, simple mod which gives slimes a slightly more noticeable role in the game, by adding a brand-new spreadable mini-biome that they inhabit.
What does it add?
When adventuring through the caves, you may come across an 'Ooze zone', a slimey patch of cave where slimes live. The walls of an ooze zone are covered in ooze blocks, a spreadable block which will occasionally spawn a single slime when a player is in range.
Spreadable?
Much like sculk, ooze blocks can spread. when an ooze-spawned slime is killed, a small patch of ooze will spread around it, causing the slimey biome to spread further!
Loot!
Some ooze zones spawn with a circular ring of rooms around the centre -- each room having a chance to contain a barrel full of useful stuff.
Here's a little showcase video that you can watch if you're interested.
