25w15a is the first snapshot for Java Edition 1.21.6, released on April 8, 2025,[1] which adds the dried ghast block, happy ghasts, harnesses, two new advancements and fixes bugs. The locator bar is also added behind an experimental toggle.
Additions
Blocks
- Found in Nether fossils in soul sand valleys.
- Can be crafted with 1 bone block and 8 ghast tears.
| Ingredients | Crafting recipe |
|---|---|
| Ghast Tear + Bone Block |
   |
- Can be mined instantly without using a tool.
- 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.
- Can be moved by pistons.
Items
- Used to spawn a happy ghast.
- Crafted out of 3 leather, 2 glass and 1 wool, the harness will have the same color as the wool used when crafting.
| Ingredients | Crafting recipe |
|---|---|
| Leather + Glass + Matching Wool |
                                  |
- Used to fly on happy ghasts.
- Can only be equipped on a happy ghast.
- Allows up to 4 players to mount the happy ghast.

- Can be re-dyed.
| Ingredients | Crafting recipe |
|---|---|
| Any Harness + Matching Dye |
                |
- Can be removed from the happy ghast using shears, but only when no players are mounted.
Mobs
- Spawned after a dried ghast gets hydrated in water.
- Can also be summoned using the command:
/summon happy_ghast ~ ~ ~ {Age:-24000}, or by using a Happy Ghast Spawn Egg on a Happy Ghast.
- Can also be summoned using the command:
- Has 20HP
× 10 health points. - Will grow up into a Happy Ghast after about 20 minutes (or faster if fed Snowballs).
- Can be tempted and fed using snowballs to speed up their growth.
- 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, it 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.
- Spawned after a ghastling grows up.
- Has 20HP × 10 health points.
- 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.
- The first player that mounts the Happy Ghast will control it, sitting in front of the Happy Ghast, just above its face.
- Pressing the forward key will make the Happy Ghast fly in the direction the player is looking.
- Pressing the back key will make the Happy Ghast fly in the opposite direction the player is looking.
- Pressing the left and right keys will strafe the Happy Ghast in the respective direction.
- Pressing the jump key will make the Happy Ghast fly directly up.
- 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.
- If the happy ghast detects players on top of it, it then ceases all movement and aligns to the closest cardinal horizontal direction.
- When not being ridden, can be tempted by players holding snowballs and harnesses.
- However, they can not be bred.
- Harness tempting only works if the Happy Ghast is unharnessed.
- 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.
- Can be burned by fire and lava, as opposed to regular ghasts.
- Cannot enter boats, but can enter minecarts.
- 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 (the home position is where the Ghastling was hydrated as a dried ghast).
- Idles around within 64 blocks from its home position in the similar way as the Ghastling.
- If wearing a harness, the happy ghast idles closer to the home position (within 32 blocks).
- The Happy Ghast will try to stay close to blocks when roaming on its own.
- Does not drop anything other than experience.
