Hallowed 'Mons
by Pannda_
Hallowed 'Mons is a Cobblemon add-on that gives nine Pokemon spooky Halloween variants, with spawns tied to pumpkins, forests, villages and nether fossils.
What it does
The add-on introduces Halloween-inspired variations of a small set of Pokemon. Nine species receive a spooky variant, and some of them spawn naturally in the world under conditions such as nearby pumpkins, night-time forests, villages or nether fossils. Mimikyu appears near pumpkins, Noibat and Noivern in forests at night, Gothitella in villages at night, Spiritomb near pumpkins at night, and Houndoom near nether fossils.
Reaper Cloth can be held in the cosmetic slot of a Pokemon, where it gives the creature a costume. The author notes that more variants are planned for later updates. The add-on needs Cobblemon to run, and it is published for Fabric, Forge, NeoForge and Quilt. The environment is server required with the client optional, so server owners install it and players may add it for the full set of visuals. Builds cover 1.20.5 – 1.21.1 and the files are released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, which is not open source.
