Datapack Craftable Spawner and Spawn Eggs (by Mtmtksvr)

Craftable Spawner and Spawn Eggs for Minecraft 1.21

Craftable Spawner and Spawn Eggs by Mtmtksvr is a Minecraft Java datapack for the 1.21.x series that adds crafting recipes for normally unobtainable spawners and spawn eggs. Its central recipe uses four copper ingots, four iron ingots, and one diamond to create a spawner, while additional recipes provide eggs for several vanilla creatures, including zombies, skeletons, creepers, villagers, sheep, cows, chickens, spiders, and blazes.
