This plugin uses my own library to work! if you want to make a plugin like this, just use my EntitySerializer Library.

Features:
/giveball - pokeballmc.giveball
=> Gives you the pokeball, the item that lets you to pick entities/mobs with an item.
=> Persistent on death.
=> Resource pack supportive (Custom model ID is 411)
=> Item can be stored in chests to essentially put your villagers or any mob inside a chest or shulker..etc.
