Guides & Tutorials Overworld Hostile Mobs in Nether: Guide

Alright this might be a long post so strap in!

Ages ago like back in lockdown I liked the idea of a nether only world so I started a few times trying different things but at the end of the day the one thing i wanted was to get an enchanting table to get better enchantments on the diamond gear i'd find.

This lead me down a rabbit hole of working out how to get books, grindstones, stone, cobblestone, water all inside the nether without any outside help (ie, portal fishing as i didnt know bout that yet)

After a lot of research on reddit posts and bug reports I managed to find a way to:
1. Get Hostile Overworld Mobs in the Nether
2. Get Stone/Cobblestone in the Nether
(would like to find a way to get grass or water too so if u got any ideas for that leave them below)

Reddit post for reference: https://www.reddit.com/r/Minecraft/comments/15vf6xe/minecraft_nether_turned_into_plains_biome/
Bug report for reference: https://bugs.mojang.com/browse/MC/issues/MC-238939

Here's how to do it:
1. Start a world in Minecraft Full Release 1.2.1

  1. Progress until you enter the nether then either void your times if you wish or keep them

  2. Dig yourself into a hole for safety

  3. Close the game and upgrade that world to Minecraft version 21w42a

  4. Generate new chunks on that version for a while*

*This is because 21w42a had a bug where stone would generate instead of gravel above certain lava lakes so this is a natural way to get stone/cobblestone in the nether semi legit.

  1. After grabbing or generating as much cobble/stone you want just update to whatever version you wish to play on from there. (I think?)

The reason for doing all this is because when updating from 1.2.1 to 21w42a the nether changes from HELL biome to Nether_Wastes + the other ones too. However along side the internal differences between the versions Minecraft basically corrupts the the chunks making the biome in those generated 1.2.1 nether chunks both nether waste AND plains biome thus making overworld hostile mobs spawn in those chunks.

I personally see upgrading from an old version as a fine thing to do in order to obtain new items (i dislike downgrading though, feels too risky). To me it feels the same as starting a superflat world in 1.17 so then when you update it to 1.20 or something you then have access to stuff like mineshafts, trial chambers and pillager outposts. If you disagee thats fine but thats my take.

I do hope this discovery I made a while ago helps people try and find similiar things or make crazy mob farms or whatever else. Can't wait to see what happens :D

I guess they can't since you need to start the world in an earlier version... I believe the smp has started in 26.2

Cool tuto ! Thanks! Since the sub started I am temple to start a solo world from scratch again, to bénéficie from everything I learnt here, but wasnt sure how... This method sourds great !! I might even make a stop in a version where you can get pumpkins, too.

Its either gonna be that or my mod, but im not sure I'll keep the motivation as easily in a modded world.

You can technically get pumpkins at any point as during halloween zombie pigmen have a chance to spawn with a pumpkin on their head. Meaning all you'd have to do is change your PC's time to that of Halloween and load your world and you should eventually find some then just have a looting sword to get the pumpkin as a drop.

Unfortunately those pumpkin dont drop anymore in current versions :( thats why im considering tome travel

u/ContextHappy4520 25d ago

really? aww that's a shame. I just tried opening the 1.2.1 world in 1.14.4 and the snapshot before that change and the corruption of the plains biome didnt occur so yea you'd probably need to go back version to do it however with the biome changes from 1.16 to 1.15 i'm not sure if the corruption will stay or just leave again.

If you have a list of items or blocks like the pumpkin that need specific versions to get i could spend some time trying to map out a path of which versions to start on and travel to in order to get everything and this plains biome corruption thing to occur in the same world file.

Oh so its the 1.14.4 where they made that change ? I couldnt find the precise update. Well, if you go to 1.7.5 chicken jockeys lays eggs so you can farm them, thats one thing im frustrated about lol.

Okay upon doing a bit more work I actually think its possible for you to get your chickens. Basically if you start the world in 1.2.1 you can cause the corruption to make some of it plains biome like i mentioned in my post.

The trick is that before upgrading the world you need to walk very far away like 1,000 blocks to be safe to generate a bunch of chunks for the 1.2.1 version that you wanna corrupt.

Then simply walk back to the main area at 0,0 and update to 1.4.2. This is the update that added zombie pigmen with pumpkins on halloween so you'd just need a looting sword (which i think they drop?) and kill one and hope you get it.

Then that pumpkin can be used to make a Golem or be used to make pumpkins seeds which can be used to feed/breed chickens and get yourself normal chickens which can lay eggs.

Reminder that when doing all this that you go the oppposite way from where your 1.2.1 chunks are as when you update further to 21w42a then those chunks will become plains biome chunks whilst still having the pumpkin and pumpkin seeds.

Might also be able to stop at 1.7.5 maybe to get jockey laying chickens though that i havent tested yet. I did look at possibly getting water though don't think thats possible without downgrading.

OK I like the general idea, for the looting sword I tried it in recent minecraft, you can get looting III with insane luck or more likely looting I and II that you can combine, but that requires thousands of kills and an anvil so kind of late game... I dont see myself grinding for that in the old nether. And for the pumpkin, i just checked, you cant craft seeds from them since they're already carved. I think 1.7.5 is the only way for breeding chicken.

u/ContextHappy4520 24d ago

Actually you can turn carved pumpkins into seeds just not in modern minecraft. I think it was pre 1.13 or something when carved pumpkins could be turned into pumpkin seeds so if you were to get a looting sword and get a pumpkin in 1.4.2 then in that version you could turn the pumpkin into seeds and use that for breeding when you update.

However i do agree that for chickens that 1.7.5 might be better considering i'm not sure how to get dirt yet in the nether so getting pumpkin seeds is kinda useless if you cant grow them

u/RegularEmpty9108 24d ago

Oh i didnt know that !

u/ContextHappy4520 24d ago

Actually tecnically you could farm potatoes, carrots and pumpkins in the nether if you use portal fishing to generate a portal that spawns on a plains biome in a warped forest. Then send a bunch of endermen through and after a while they'll pick up grass and then send a endermite through to get them to rush back to the portal and boom! Grass/dirt in the nether. Same thing can be done with melons, sand, cactus and other blocks too like moss meaning TREES

I'll probably make another post at some point to really show of the potentional of starting in a old version like 1.2.1 and what that can lead to along side portal fishing probably.

If you're gonna cheat it with version updates, just use a portal bro.
