EGGS!

EGGS! is a resource pack that adds 4 new spawn eggs to the game, the Illusioner, Giant, Killer Bunny and Charged Creeper spawn egg. The way it works is simple. The following 4 commands will give you a custom spawn egg that spawns the corresponding mob. No mods or datapacks needed.

Charged Creeper Spawn Egg:

/give @s creeper_spawn_egg[entity_data={id:"minecraft:creeper",powered:1b},item_name="Charged Creeper Spawn Egg"] 1

Illusioner Spawn Egg:

/give @s pillager_spawn_egg[entity_data={id:"minecraft:illusioner"},item_name="Illusioner Spawn Egg"] 1

Giant Spawn Egg:

/give @s zombie_spawn_egg[entity_data={id:"minecraft:giant"},item_name="Giant Spawn Egg"] 1

Killer Bunny Spawn Egg:

/give @s rabbit_spawn_egg[entity_data={id:"minecraft:rabbit",RabbitType:99},item_name="Killer Bunny Spawn Egg"] 1

Executing these commands with the resource pack on and working will give you the custom spawn eggs. If anyone has suggestions for extra spawn eggs, please suggest ideas on the GitHub page.
