No Superflat Slimes Mod (1.21.3, 1.20.6) – Slimes No Longer Spawn In Superflat Worlds
If you have played on a superflat world in Minecraft, you would know that the world would be filled with a lot of slime mobs. This is always the case when you generate a superflat world. No Superflat Slimes Mod is here to change that. As the name suggests, this mod makes it so that slime mobs no longer infest your superflat worlds.
Features:
- Prevents slime mobs from infesting superflat worlds.
- Slimes spawned using spawn eggs will not be killed.
- If you want to spawn a slime with /summon, give it the custom EntityTag “dontkill” and it won’t die.
