Pixellated Pocket Spirits Resource Pack Wiki & Guide

Yes, you need Cobblemon installed for the pack to function, since it reskins Cobblemon blocks, items, and creatures. The pack is designed as a resource pack layer on top of Cobblemon, so it won't do anything without the mod present.

It depends on load order and what the other pack modifies. If another pack also changes Cobblemon textures or items, whichever loads last will override the other. You may need to test combinations or use a resource pack merger if conflicts occur.

The custom creature models like Cherry Blossom Torterra apply automatically once the pack is loaded—you don't need to do anything special. The reskins replace the default Cobblemon creature models for all instances of those Pokémon in your world.

Resource packs are all-or-nothing when loaded, but you can create a custom pack that combines elements from multiple sources if you're comfortable editing texture files. Otherwise, you'll need to use the full pack as-is or find an alternative that matches your preferences.
