Mobs To Eggs
Mobs to Eggs is a plugin on PigSMP that allows players to capture, move and release various different mobs.
Capsules save mob NBT data, this means that names, villager trades and other information is saved when the mob is captured so that you will not loose villager trades or discounts making them a very powerful tool.
Mob capture capsules can be obtained either by winning them from the Vote Crate at /warp Crates or you can craft them in a crafting grid with the bellow recipe.

Mob Capsule Recipe
Capturing mobs is easy just punch them (Left Click) and they will be captured inside of a mob spawn egg that will drop to the ground. You can store this egg for later or take it to a new location to release the mob into e.g. Trading Hall or Mob Farm.
