For Gimmighoul honestly it'd be pretty easy to just bring over the same exact gimmick. Find roaming gimmighoul or beat up chest gimmighoul, both presumably scattered around hyperspace, and earn the CoinsIt really interests me how they will handle Gholdengo and, even more, Meltan and Melmetal and if we will be able to evolve to them in-game.
For Meltan...
Option 1: Meltan isn't actually available in the DLC proper; it's just something you transfer over. In this situation I think they still don't let you evolve the thing just like in SWSH. It's only here out of obligation for having Melmetal
Option 2: Meltan is available in the DLC proper. For lore reasons, it would be easy to give it the same method as Gimmighoul just with some Meltan "material", but I think they'd only want one of those around at once so probably just make a new item you give it instead. Make it the Mystery Box.
