Oops! All mobs.
by deinomodder
Oops All Mobs changes which creatures spawn in the Overworld, moving Nether and End creatures into regular world generation.
What it does
Creatures that normally stay in the Nether or End can appear on Overworld terrain once the mod is loaded, so the dimensions no longer keep their own inhabitants apart. Striders join Overworld spawning too, and each world ends up with a mix that differs from one playthrough to the next. The mod is server-side only, so players join without installing it, and it is published for Forge and NeoForge across six game versions, 1.20.1 – 1.21.5, under All rights reserved.
Key features
Nether and End mobs in the Overworld
Nether and End creatures spawn in ordinary Overworld terrain alongside the usual wildlife.
Striders in the Overworld
Striders spawn in the Overworld, adding a new source of encounters to lakes and rivers.
Mixed dimensional spawns
Creatures from several dimensions share the same spawn pool, so exploring the Overworld can bring unfamiliar threats.
Compatibility
Latest build for each game version and loader.

What the author says
The dimensions have collapsed... and the Overworld will never be the same. The barriers between realms are gone. The Nether’s flames and the End’s void have spilled into your once-safe world. Nowhere is safe.
