With this data pack, you won't know which mob drops what. If you need food, figure out which mob will give it.

The mobs that got randomized are zombie, sheep, cow, pig, squid, donkey, horse, llama, iron golem, spider, chicken, rabbit, cod, salmon, enderman, piglin, hoglin, pillager, shulker, phantom, blaze, creeper, ghast, magma cube, skeleton, slime.

If you wish to see the rest of the mobs randomized too, tell me in the comments.
