No Superflat Slimes
by o-Peepo
No Superflat Slimes stops slimes from spawning in superflat worlds, and it applies to both generated and player-placed slimes in those worlds.
What it does
Superflat worlds normally let slimes spawn on their flat surface, which some players find distracting in custom or minigame maps. No Superflat Slimes removes that spawning so the flat terrain stays free of slimes. The mod runs on Fabric, Forge and Quilt, and it is published as a data pack as well.
The server needs the mod, and players can join without installing it. Installation on a dedicated server means placing the file in the mods folder and restarting, while a data pack version can be placed in the world's datapacks folder and loaded with a reload or a restart. Files target 1.17 – 26.3, and the latest build for 26.3 is dated 2024-06-15 on the beta channel. The code is covered by All rights reserved, so the mod is not open source.
Slimes created by spawn eggs are still killed by the mod's rules, and a slime summoned with a custom EntityTag set to dontkill will not die.
Key features
Superflat slime removal
Slimes no longer spawn on the flat terrain of superflat worlds, keeping those maps clear of them.
Spawn egg handling
Slimes created from spawn eggs are removed under the mod's rules, so eggs do not reintroduce them.
Protected summons
A slime summoned with a custom EntityTag set to dontkill is kept alive, letting map makers place slimes on purpose.
Data pack option
A data pack build can be dropped into a world's datapacks folder and enabled without installing a mod.

Use cases
Custom map makers
Builders who create superflat adventure or parkour maps can keep slimes out of their terrain.
Server owners
A server running superflat hub or minigame worlds can enforce the no-slime rule on the server side.
Who it’s for: The mod suits map makers and server owners who run superflat worlds and want the flat surface free of slimes. Players who only use standard worlds have no need for it.
How it compares
Remove Superflat Slimes is a Fabric-only server-side mod for 26.2, with All rights reserved and no open source code. Superflat Revamped covers 1.21.4 and runs on Fabric and Forge as a server-required mod under All rights reserved. Superflat Dimensions is open source under the MIT License and spans 1.19 – 1.21.10 across four loaders, so it targets a much wider version range than this mod.
