How to Spawn Custom Planeta Cobblemon Pokémon Using Commands
The Planeta Cobblemon data pack adds extra Pokémon models, but none of them appear in the wild. Every creature has to be summoned manually, so learning the spawn command is the first thing you should do.
Finding the Right Command
Cobblemon uses its own spawn command rather than vanilla /summon. Open chat and type /pokemonspawn followed by the species name, or use the Cobblemon spawn syntax your version supports. As you type the species name, autocomplete should suggest valid entries from the data pack, such as roaringmoon, ironcrown, ironboulder, heatran, terrakion, virision, dedenne, trubbish, or electrike. If a name does not autocomplete, the model likely is not registered.
Spawning and Positioning
Stand where you want the Pokémon to appear, then run the command. Most Cobblemon spawn commands place the creature in front of you or at your crosshair. If nothing shows up, check that you typed the species name in lowercase with no spaces. You can also add a level argument if your command version supports it.
Troubleshooting
If the command errors out, confirm the data pack is actually loaded by checking your world's data packs screen. A missing or disabled pack means none of these species exist in the registry, and no command will work until it is enabled.
