About:

It's simple! Mutant Creeper Overhaul is a resource pack that replaces the textures of Mutant Creeper from Mutant Monsters to fit better with the Creeper Overhaul mod!

Additional notes:

With either Optifine (not recommended) or Entity Texture Features, you get three variant textures offering slightly different coloration of the Mutant Creepers (seen in the image above, the first Creeper is the default variant, others will not spawn without the ETF or Optifine).

Installation:

Just drop the file into your resource packs folder, enable it, and enjoy!
Disclaimer:
The resource pack does not require Creeper Overhaul to be installed, but why would you use it without it?
