Minecraft Java Edition - Snapshot 25w15a

Snapshot on a Tuesday? Yes! From now on we will be moving snapshots to the same weekday as full releases, Tuesdays.

This week we are releasing the first snapshot of the second game drop of 2025, including the happy ghast, ghastling, dried ghast and ghast harness. Experience soaring new gameplay thanks to the happy ghast, and discover how to raise one of your own – from retrieving a dried ghast block from the Nether to submerging it in water in the Overworld to spawn a ghastling. We are also adding the locator bar to Java this week, you can finally easily find your friends when you are out adventuring.

Take your first test flight with the happy ghast, craft your own dried ghast – and send us your feedback!

New Features

  • Added Dried Ghast block
  • Added Happy Ghast mob
  • Added Harness items
  • Added new advancements

Dried Ghast block

  • Can be found in the Nether in Nether Fossil structures
  • Is crafted with 1 Bone Block and 8 Ghast Tears
  • When waterlogged it undergoes 3 state changes over about 20 minutes until it spawns a Ghastling mob
  • Makes sounds and shows particles depending on the 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

Happy Ghast mob

Ghastling

  • Ghastling is a young version of the Happy Ghast mob
  • Spawns from a Dried Ghast block that has continuously been waterlogged for about 20 minutes
  • After spawning, the 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
  • Can be tempted and fed using Snowballs
  • Will grow up into a Happy Ghast after about 20 minutes (or faster if fed Snowballs)

Happy Ghast

  • The adult Happy Ghast is a new flying mount that can carry up to four players
  • Grows up from a Ghastling after about 20 minutes (or faster if the Ghastling is fed Snowballs)
  • Can be equipped with a Harness and then be mounted by up to 4 players
  • Tempted by Snowballs and Harness
    • Harness tempting only works if the Happy Ghast is unharnessed
  • Has no panic behavior when taking damage
  • Cannot be bred
  • Slowly regenerates health, with regeneration speeding up during rain, snow or when flying at the same height as clouds are rendered
  • 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
    • Pressing the sneak key will make the player dismount the Happy Ghast
  • 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 of the Happy Ghast
  • 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
  • 3rd person camera is moved back when player is mounted on the Happy Ghast
  • 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
  • If players dismount midair, the Happy Ghast will descend towards the ground before it resumes roaming
  • Cannot enter boats
  • 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

Ghast

  • Updated Ghast texture

Harness items

  • Harness is a new item that can be equipped on a Happy Ghast to allow players to ride it
  • It is 16 new items, one for each color
  • Crafted out of 3 Leather, 2 Glass blocks and 1 Wool block, the Harness will have the same color as the Wool block used when crafting
  • Can be re-dyed
  • Can only be equipped on a Happy Ghast
  • Allows up to 4 players to mount the Happy Ghast
  • Can be removed from the Happy Ghast using Shears but only when no players are mounted

Advancements

  • Added new "Stay Hydrated!" Husbandry Advancement when a Dried Ghast Block is placed into Water
  • Added "Heart Transplanter" Adventure Advancement that is unlocked when a player places a Creaking Heart with the correct alignment between two Pale Oak Log blocks

Experimental Features

  • This snapshot introduces a new experimental Feature Toggle that adds a locator bar to find your friends easily. You must turn on this Feature Toggle in the Experiments Menu when creating a new world if you want to test the locator bar. You can find more information about Feature Toggles here.

Locator Bar

The Locator Bar is an experimental new UI element for players that displays the direction of Waypoints.

  • This experiment allows servers to manage Waypoints and their connections with Players
  • By default, all Players transmit a Waypoint from themselves, and all Players receive all Waypoints; allowing players to locate other players in multiplayer
  • The Locator Bar will display colored indicators when the camera is facing within 120 degrees towards a Waypoint. If a Waypoint is above/below the camera's viewport (the screen) an up/down arrow will display
  • Any Waypoint that is determined to be a Player or Mob that belongs to a Team then the color indicator will match the Team color

Player Changes

  • Crouching will hide the player, preventing them from appearing on the Locator Bar of other players
  • Spectators are only visible to other spectators on the Locator Bar

Item Changes

  • The following items will hide players when worn in the head slot:
    • Carved Pumpkin
    • Skeleton Skull

    • Dragon Head
    • Piglin Head

This is a new command for querying and modifying waypoints.
