In this datapack, you can craft mob eggs in survival Minecraft. The mob eggs are crafted using the certain mob's drops and a totem of undying (i.e. a zombie spawn egg is crafted using rotten flesh and a totem of undying). You can also take advantage of these mob eggs by crafting a monster spawner. This datapack is very small, but it can help a lot in survival minecraft worlds.

If you are confused about the crafting recipes, look at the pictures I have provided.
