Change Happy Ghast Color to Lighter Blue with Swirling Patterns

I suggest changing the Happy Ghast’s color to a lighter blue to better distinguish it from regular Ghasts and fit the Overworld’s aesthetic. Additionally, adding swirling patterns, similar to the Breeze mob, could give it a more magical, dynamic look. This would make the Happy Ghast more unique and visually appealing in both the Overworld and Nether.
