Bat Spawn Egg
minecraft:bat_spawn_eggThe Bat Spawn Egg instantly spawns a single bat when used on a block, and is available only through Creative mode or commands like /give. Bats are small, neutral flying mobs that do not attack players. If you stand far enough away and use the egg on the underside of an opaque block, the spawned bat will hang upside down from it.
