Ingredients	[hide]Crafting recipe
Ghast Tear + Bone Block

• When waterlogged, it undergoes 3 states over about 20 minutes until it spawns a ghastling mob.
• Makes sounds and shows particles depending on state.
• If mined during the waterlogging, it will revert to its "dry" state regardless of what state it has reached during waterlogging.
• Will revert states back to its initial "dry" state when it is taken away from being waterlogged, using the same time scale.

Items

Happy Ghast Spawn Egg

• Used to spawn a happy ghast.

Harness

• Crafted out of 3 leather, 2 glass and 1 wool, the harness will have the same color as the wool used when crafting.

  • Can only be equipped on a happy ghast.
  • Allows up to 4 players to mount the happy ghast.

Mobs

Ghastling

• Spawned after a dried ghast gets hydrated in water.
• Can be fed snowballs to speed up their growth.
• Can be summoned using the command: /summon happy_ghast ~ ~ ~ ~ ~ minecraft:spawn_baby.
• After spawning, a ghastling will try and follow:
  • Players within a 16-block radius.
  • Or an adult, non-aquatic passive mob (and some neutral mobs) within a 16-block radius.
• If no player or suitable mob is close around the ghastling will idle around within 32 blocks from its home position (where it spawned or last was interacted with).
  • It will reset its home position if it is moved more than 16 blocks away from the border of its home area.

Happy Ghast

• Spawned after a ghastling gets fed enough snowballs.
• A rideable entity, which can be equipped with a harness and ridden by up to four players.
  • When a player mounts, the goggles on the Happy Ghast go down to cover its eyes, indicating that it now can be controlled
  • Players mounted after the first player piloting the Happy Ghast are placed in slots on each side of it, starting clockwise from the first player
  • Pressing crouch button dismounts the player on top.
  • 3rd person camera is moved back when player is mounted.
  • If players dismount midair, the Happy Ghast will descend towards the ground before it resumes roaming
• Can be stood on, similar to a shulker.
  • If the Happy Ghast detects players on top of it, it then ceases all movement and aligns to the closest cardinal horizontal direction
    • This happens regardless of it having a Harness equipped or not.
• When not being ridden, will approach players holding snowballs.
• Has no panic behavior when taking damage.
• Slowly regenerates health, with regeneration speeding up during rain, snow or when flying at the same height as clouds are rendered.
• Cannot enter boats
• When there are no players mounted or walking on the Happy Ghast, the goggles go up and the Happy Ghast starts to roam around the home position.
• Idles around within 64 blocks from its home position in the similar way as the Ghastling.
