Ancient Dried Spawn Eggs

Ancient Dried Spawn Eggs can be found underground, most commonly in the Mining Dimension. If placed in a Crafting Table with a Water Bucket it will create the corresponding Spawn Egg, with the exception of high-level boss eggs, for which you need to combine 9 Ancient Dried [Boss Name] Egg Parts in a Crafting Table to create the respective egg.

Example

Ancient Dried Cow Egg+Water Bucket=Cow Spawn Egg
