Spawn Eggs are an Item only obtainable in Creative Mode (but can be transferred to Survival Mode from Creative Mode), and hold the qualities of spawning a certain Mob, depending on the Spawn Egg used. Hostile Mobs will not spawn from Spawn Eggs if the difficulty level is set to Peaceful. All the Spawn Eggs are available in all versions of Minecraft, including the Pocket Edition starting with Update 0.9.0.
The Mobs that cannot be spawned with Spawn Eggs are Spider Jockeys, Ender Dragons, Giants, Snow Golems, Iron Golems, Withers, Tamed Wolves, and Zombie Villagers. Though the Spider Jockey cannot be directly spawned, there is a very small chance a Spider Spawn Egg will actually spawn one. If a Spawn Egg is named via an Anvil, the name of the Spawn Egg will be transferred onto that Mob and will be displayed in a similar manner to that of a player's tag. In versions before 1.5, Mobs could not be named. Eggs are actually two textures, one being a blank egg and the other being spots, which are on top of the blank egg. Both textures are white but have a special type of coding.some of the mobs like pumpkin snowman, etc don't spawn from eggs
Unlike other objects, when a Spawn Egg is placed into a Dispenser and then activated, it will summon the Mob based on the egg inside of it.
A Spawn Eggs ID is 383 and can be obtained using the "/give" command, but this will only give the player "spawn(a white egg with white spots that cannot be used)". In the PC edition Spawn eggs can be obtained in creative by middle clicking a mob, while in the PS3 editon, they can be obtained from the creative mode interface.
