Elder Guardian Spawn Egg is a Creative-mode item that instantly spawns an Elder Guardian wherever you right-click. Added to Minecraft Java Edition in version 1.8 and present in Bedrock Edition, Elder Guardian Spawn Egg cannot be crafted, mined, or obtained in Survival — it appears only in the Creative inventory or through the /give command (minecraft:elder_guardian_spawn_egg). The egg shows the Guardian's signature teal body with darker spot markings, matching the Elder Guardian's washed-out grey-green coloring.

Right-clicking with Elder Guardian Spawn Egg summons a hostile Elder Guardian with 80 health that fires a laser beam, retaliates with spikes, and projects Mining Fatigue III onto every player within 50 blocks. A spawned Elder Guardian behaves exactly like one from an ocean monument: it always drops a single wet sponge on death, along with prismarine shards, prismarine crystals, and raw cod. Builders and map-makers use Elder Guardian Spawn Egg to populate custom aquatic arenas or to test sponge and prismarine farms without raiding a natural monument.
