Pokemon of Different Sizes with Cobblemon PokeSizes
Cobblemon PokeSizes is an interesting datapack that solves one of the main issues with the Cobblemon modpack. Did it seem strange that all Pokemon were the same size? I encountered this too and decided to fix the situation myself!

What does this datapack offer?
This mod introduces a system of size variations for Pokemon. Now they can spawn in three different dimensions:
- Normal - standard size from base Cobblemon
- Small - reduced version of any Pokemon
- Large - enlarged specimens
Notably, the size is chosen randomly when the Pokemon spawns in the world. Currently, determining the size without viewing the entity's NBT data is impossible - this is worth considering when using.
WHAT'S NEEDED FOR WORK
For proper operation, both sides (client and server) need to install:
- Pehkui mod version 1.19.2 or newer
- Main Cobblemon modpack

Technical note: for installation, place the datapack in the world/datapacks folder of the selected world.
