Spawn Egg

A Spawn Egg is an item added in the weekly Pre-release 11w49a, and later included in the 1.1 Official Release, which is only accessible in Creative Mode. It allows the player to spawn a variety of mobs on command, although some mobs are not available in Item Selection for certain reasons. Hostile mobs can not be spawned on Peaceful difficulty. The player may spawn their chosen mob by right clicking whilst holding the egg, aiming it at an open space.

Available Mobs
Spawn Eggs of normally unavailable entities can be obtained by using the SMP Command /give. When using this method, the damage value of the egg spawned pertains to the Entity ID of the entity it makes. Not only does this allow the player to spawn unavailable mobs such as Giants, it allows them to spawn Minecarts and even Primed TNT.


 * Example: /give PLAYERNAME 383 1 120 would give the player a Villager Spawn Egg.

(You can also set 'damage' value to 120, 63, 95, 53, ect. to create a spawn egg in INVedit.)

Trivia

 * Prior to 12w01a, There was only one texture for the Spawn Mob eggs. The game hue shifted this texture to create different colors. The unaltered sprite was used by Spawn Mooshroom.
 * In 12w01a, the egg and its markings had their textures separated in order to allow them to have entirely different colors. This allowed their colors to be changed to better suit the mobs themselves.
 * Since they are not used as projectiles, attempting to fire them from a Dispenser will result as them simply being dropped as an item.
 * Mobs spawned via this item act the same as normally spawned ones. As such, hostile mobs will despawn if the player ventures too far.
 * Eggs spawned using the /give command which spawn entities other than the ones already provided will always be white with slightly darker spots.
