Mojang has unveiled an exciting addition to Minecraft: the dried ghast block. Players can either find this block in the Nether or craft it, ultimately transforming it into a ghastling and, eventually, a happy ghast. This update also introduces a new advancement called Stay Hydrated!.
How to Achieve the Stay Hydrated! Advancement in Minecraft
Step 1: Obtain a Dried Ghast Block

Your journey begins with acquiring the dried ghast block. One option is to locate it in the Nether, specifically in the Soul Sand Valley biome, where it can often be found near Nether fossils—an uncommon structure unique to this area.
If you’re unable to find the block naturally, you can craft it on a workbench. To do so, gather eight ghast tears and one bone block. Ghast tears can be obtained by defeating the original Nether ghasts, while a bone block can be created by combining nine pieces of bonemeal.
Step 2: Submerge the Dried Ghast Block in Water

During the first Minecraft Live event of 2025, the developers announced that placing the dried ghast block underwater will initiate its transformation process into a ghastling over a period of approximately 20 minutes.
To proceed with the advancement task, simply immerse the dried ghast block in water. You’ll instantly unlock the Stay Hydrated! achievement—an aptly named quest, considering you are nurturing the block into a ghastling.
Once the 20-minute mark passes, watch as the dried ghast evolves into a ghastling, a smaller variant of a ghast that will mature into a happy ghast. Notably, happy ghasts represent a unique, friendly variant that allows players to ride them using a harness, enhancing the overall gameplay experience.
