This mod simply makes zombies (any type, including zombified piglins and zoglins), slimes and phantoms breedable.
What items can I use to breed?
All breeding items can be changed via datapacks, here's the defaults!
Drowned: Any type of vanilla fish, any type of raw vanilla meat, rotten flesh and spider eyes.
Husk: Any type of raw vanilla meat, rotten flesh and spider eyes.
Magma cube: See the next point.
Phantom: Phantom membranes.
Slime: See the next point.
Zoglin: Same as drowned.
Zombie: Same as Husk.
Zombie Villager: Same as Husk.
Zombified Piglin: Same as Husk.
What about slimes and magma cubes?
They can eat anything, in their case, the tag is used to blacklist an item of being used to breed them.
