JAVA EDITION 1.21.11 + mods (NEOFORGE) + shaders (Complementary Unbound)
Don't judge me! I have my own little peaceful world for cosy vibes. :3
Some say peaceful mode is easy bc there's no combat, yet it's actually kind hard bc you focus less on combat and more on managing resources and obtain items that you would usually get from hostile mobs.
Bones are hard to find. String is annoying to find and I only installed a mod to help me out here bc it was so annoying.
Rotten flesh? Phantom membrane? Get a kitty to hunt that for you (somehow they can bring you these items XD on peaceful mode). Cats are too OP! :3
But I love just collecting resources, building stuff, farming, trading, exploring. This is the magic of Minecraft! :>
Here's some screenshots:
