Spawn Egg

A spawn egg is an item used to spawn mobs directly.

Obtaining
Spawn eggs can only be obtained in Creative mode or using commands. In Creative mode, the player can press on an existing mob to obtain their respective egg. Spawn eggs are also available in the Creative inventory. There are 58 eggs in the Java Edition, 59 eggs in the Bedrock Edition and PlayStation 4 Edition, and 41 eggs in the New Nintendo 3DS Edition.

Commands
Spawn eggs can be obtained by using. See here for all available spawn eggs and commands. For some reason, the spawn egg command never works, thus not allowing the player to have it. In earlier versions of the game, the player could spawn an entity with that spawn egg to spawn rare mobs such as the wither boss.

Any spawn eggs not listed in the table below cannot spawn entities. They will instead make a sound as though an arrow has been shot. These eggs will be the default color, $$ white with gray spots, while $$ it will be pitch black. When a player hovers over the image with their mouse the name of the egg is "Spawn ". This egg has no specific properties and cannot spawn any mob, except for Bedrock Edition in which some "hidden" spawn eggs that spawn other entities like primed TNT and wither skulls. They can only be obtained via inventory editing, or with some add-ons, default blank spawn egg texture used on custom mobs if not defined in the resource pack.

Usage
A spawn egg is used by pressing on any surface (top, bottom or side) with the egg. When used on a top surface, the egg's mob will appear with its feet immediately adjacent to the surface.

Spawn eggs are not thrown (unlike normal eggs); the player must be within normal range of the block to use the spawn egg. Hostile and neutral mobs (except wolves, polar bears, pandas, dolphins, llamas, vindicators, evokers, and shulkers ) spawned while on Peaceful difficulty will be created, but then instantly deleted from the world.

The surfaces of blocks are prioritized for spawning; if none are within reach, mobs can also be spawned in water.

Dispensers
A spawn egg fired from a dispenser will spawn the mob directly in front of the dispenser.

Baby mobs
If a passive mob has a baby form, and the player its spawn egg on an adult, it will spawn a baby version of that mob, rather than an adult. Other mobs such as evokers, vindicators and vexes don’t breed. Certain mobs such as polar bears and zombies, while not being able to breed, do have baby variants; using a spawn egg on these will not spawn a baby variant (with the exception of polar bears, skeleton horses and zombie horses).

Spawners
Any spawn egg can also be on a spawner to change the mob the spawner spawn. $$, spawn eggs for any of the fish mobs will only spawn them if the spawner is waterlogged.

Renaming
Spawn eggs can be renamed on an anvil, and when used will spawn mobs with that name appearing over their head. Their names can only be seen if they are aimed at from four or fewer blocks away. This name will also appear in death messages from the mob killing a player. If the player renames a spawn egg by the names described below, the mob will appear described below. If the player renames a rabbit spawn egg "Toast", the secret skin of the rabbit appears when the egg is used. When a spawn egg is named "Dinnerbone" or "Grumm", it will cause the mob to appear upside down and show the given name above it. Renaming a vindicator "Johnny" will cause it to act hostile to all mobs except to few mobs such as another illager.

Java Edition

 * : The item's tag tag.

Bedrock Edition

 * : The item's tag tag.
 * : The entity's string ID.

When using the command to give a spawn egg, it requires the numeric ID of an entity; for example:  would give an egg that spawns a creeper. For reference, see Bedrock Edition data values for a complete list of entity IDs.

Eggs can be given not just for mobs listed in the table above, but for a few other entities. These eggs will be uncolored (white with gray spots) and will be called by unlocalized placeholder names, or simply, "Spawn".
 * The snow golem (21), iron golem (20) and item (64) spawn eggs can be given, but will spawn nothing.
 * The ender crystal spawn egg (71) produces an end crystal.
 * The boat (90) egg will place a boat on the ground.
 * Using any other entity ID will fail to give the egg.
 * The painting and player spawn egg instantly crashes the game.
