The ghastling is the happy ghast's baby variant in Minecraft. This creature was added to the title with the Chase the Skies game drop.

In Minecraft Java Edition, there is a small chance that certain hostile mobs can spawn with armor parts or any item in their hands.

In Bedrock, you can summon it directly by typing slash summon Warden, while on Java, the command to summon it is Minecraft colon Warden.
