Improved Happy Ghast Mod Wiki & Guide

Happy Ghasts are automatically tameable in this mod—simply hold any interaction item (brush, cookie, brown mushroom, honey bottle, or goat horn) in your main hand and right-click the ghast to apply an upgrade. Once you've interacted with it, it becomes your companion.

Yes, you can ride your Happy Ghast as a flying mount. The mod ensures you stay seated even when moving through water, unlike vanilla behavior that would knock you off.

Right-clicking a second time with the same item removes that specific upgrade and reverts the ghast back to normal for that mechanic. For example, using a brush twice will toggle wandering behavior on and off.

Bind a goat horn to your ghast by right-clicking it with the horn, then blow the horn whenever you want to summon your companion directly to your location—this works even across different dimensions.
