Spawn eggs on display. A spawn egg is an item that may be used to spawn mobs directly. It allows the player to spawn a variety of mobs on command, although some mobs are not available. There are 27 eggs available in total without mods or hacking (28 in planned versions) and 22 in pocket edition.ata values [edit | edit source].
