In the "Chase the Skies" update of Minecraft, players can find and tame a new mob called the Happy Ghast. To find a Happy Ghast, players must locate a Dried Ghast in the Soul Sand Valley biomes or obtain it through Piglin trades or crafting. They can then rehydrate the Dried Ghast in water to create a Ghastling, which is tamed by throwing a total of 10 snowballs at it. Once tamed, players can craft a harness for the Happy Ghast using 3 leather, 2 glass blocks, and 1 wool block.
The Happy Ghast can carry up to four players, with the first rider controlling the flight direction. Players can dismount mid-air and stand on the Happy Ghast’s head. It can be used for aerial scaffolding, mobile transport, group travel, and creative showcases. Players are advised to build a Happy Ghast station for easier remounting.
Happy Ghasts are vulnerable to fire damage and hostile ghasts, and they wander within a 32-block radius when harnessed. The harness can be removed with shears, and players have created travel systems using Happy Ghasts in minecarts.
