This datapack ensures that all Happy Ghasts always remain in their baby form as long as they have one of the following names:
While named this way, they cannot grow using snowballs. The effect also applies retroactively to any Happy Ghasts that have already grown. However, they will lose their harness.
If you want them to grow again and regain their harness, simply rename them with a Name Tag, or remove their custom name using:
/data remove entity <UUID> CustomName
Replace <UUID> with the Ghast’s UUID (for example, 00000000-0000-0000-0000-000000000000). You can obtain the Ghast’s UUID by looking at it while typing the command, Minecraft will recommend it for you along with selector arguments like @a, @e, @p, @r, and your own username.
