[Cobblemon] Jet and Lapori's Pokemon Big and Small
by JetSetter
Jet and Lapori's Pokemon Big and Small is a Cobblemon addon that adds a three-stage evolution line for each new species, centered on Kanto and Alola pre-evolutions.
What it does
The addon focuses on three-stage lines. Its only release, 1.1 for 1.21.1, covers the first generation, and the goal is to build out the full set. New species are catchable and can be trained and evolved in the usual Cobblemon way, and several sit in the pre-evolution lines of Rattata, Sandshrew, Paras, Venonat, Meowth, Psyduck and Growlithe. Some Kanto and Alola forms are tied to time of day, friendship, a level threshold and the biome type where the Pokemon appears.
Spawns depend on the biome. Some species turn up in grasslands, spooky or swamp biomes, arid areas or lush mushroom biomes, and a few appear at night or below Y=0 in the overworld. Several entries are based on beta designs or on fakemon from the author's other projects. The addon requires Cobblemon, and its datapack work is loaded through the mod folder. Installation is on the server, and players who join a server that runs it need nothing extra. Files are published for Fabric only, for 1.21.1, and the code is released under All rights reserved, so the addon is not open source.

How it compares
Cobblemon Alphas runs on Fabric and NeoForge for 1.21.1, with the server required and the client optional, and it is released under the MIT License. CobblemonBahaviours is Fabric only for 1.21.1, is server-side only, and is released under the MIT License. Jet and Lapori's addon is released under All rights reserved, so it differs from both in license terms.
