Spawn Eggs are an Item usually only obtainable in Creative Mode or with commands, which allows the player to spawn a particular type of mob to which the egg type corresponds. It is possible to transfer a spawn egg to Survival Mode , from Creative Mode. In addition, two spawn eggs for Wolves are found in the tutorial world of the PS3 edition . All Spawn Egg types are available in all versions of Minecraft if the mob of the Spawn Egg in question has been implemented.The mobs who have spawn eggs that can only be obtained by use of commands are: the Ender Dragon , Giant Zombie , Snow Golem , Iron Golem , and Wither . Spider Jockeys cannot be directly spawned, but there is a very small chance that a Spider Spawn Egg will spawn one. Zombie Villagers can rarely be spawned from a Zombie Spawn Egg. Skeleton Spawn Eggs have an 80% chance of spawning a Wither Skeleton when used in The Nether .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 Name Tag . In versions before 1.5, Mobs could not be named. Spawn Eggs' appearance are that of a blank egg covered in spots. The color of the spots vary, based on the type of mob which that particular egg will spawn.Unlike other objects, when a Spawn Egg is placed into a Dispenser and then activated, it will spawn the mob which is inside the egg.A Spawn Egg's ID is 383 and can be obtained using the "/ give " command. However, this will only give the player a white egg with white spots, which cannot actually be used, unless the Player specifies the data tag. In the PC edition, spawn eggs can be obtained in creative mode by middle clicking a mob, while in the PS3 edition, they can be obtained from the creative mode interface.
Whenever a passive adult mob is right clicked while holding a spawn egg of the same animal type, it will produce a baby version for any mob that has one, excluding Squids and Bats .
In Minecraft 1.4.4, whenever a baby version of a Villager is spawned, it would always produce a farmer villager child. This was later fixed.
Baby Wolves will spawn sitting if spawned using spawn eggs will produce pups that are sitting by default. This can cause a glitch to where the pups move while sitting if the player exits and re-enters the game.
As of 1.5 the player can rename eggs, and when killed by that Mob, the game would say " [Player] was Killed by [Name of Mob] " (E.g. Notch was Killed by Herobrine).
In 1.6.1, a discoverable coded feature was added: If a Mob's Spawn Egg is renamed with an Anvil or Name Tag , and is called "Dinnerbone" or "Grumm", it will be flipped upside-down. Any upside-down mobs will have right-side-up effects on them (e.g. a Zombie named Dinnerbone burning will be upside down, but the fire on it will be right-side-up).
If the player uses a Skeleton Spawn Egg in The Nether , it has a 80% chance of spawning as a Wither Skeleton.
Naming a sheep spawn egg "jeb_" will cause the Sheep's wool to be rainbow colored in 1.7.
A Donkey and Mule spawn egg are available in the Console Editions of Minecraft as an exclusive feature.
