Base: old working png-stalkers-v2-forge-1.20.1.jar
Changes:
- Kept original Jester textures and behavior unchanged.
- Replaced other old entity textures with the new PNGs.

Mapping:
- bone_mauler command now visually uses Red Stalker

Commands stay the same as the old working jar.
No new music changes were added.
