UPD 1.5.1: Added the leash feature

Happy Ghast

This mod introduces friendly Ghast companions inspired by the Live features.

Core Features:

Friendly Mobs: Adds the peaceful, rideable Happy Ghast and its baby form, the Ghastling. They won't attack players and don't despawn. Iron Golems, Snow Golems, and Guard Villagers will not target them.
Ghastling Growth:
- Find Dried Ghasts generating near Nether Fossils (in various Nether biomes).
- Waterlog a dried ghasts to start hatching (takes about 1 in-game day). The incubator shows visual stages (Dried, Neutral, Happy).
- Use Ghast Tears on a waterlogged dried ghast to speed up hatching.
- Right-click a dried ghast with a Stick to check progress.
- Feed hatched Ghastlings snowballs to heal them and significantly speed up their growth into a Happy Ghast.
Riding & Transport:
- Equip adult Happy Ghasts with a harness (found or crafted) to ride them.
- Control flight with Space (ascend) and C (descend).
- Ride with friends: Happy Ghasts can carry up to 4 players.
- Adjust flight speed using the /ghastspeed <multiplier|reset> command (requires permissions).
Customization:
- Use standard colored harnesses, dye them, or remove them with shears.
- Create custom harnesses (single-player only via /ghast createharness command and GUI). Add your own 2:1 ratio textures for saddles, glasses, and accessories to the happyghast_textures folder.
Other:
- Includes spawn eggs for both mobs.
- Features custom sounds for Ghasts, Ghastlings, and the incubator.
- Extended interaction range for easier mounting.
