>>27495819>>27495217>Swarms I've always just considered "Swarms" as migrations, you know?
Take for instance the Remoraids of Johto: They swarm a very specific fresh water lake on Route 44 and I know it "looks" small in the games, but it's big enough to have it's own pokemon on the little island in the center.
Maybe they do this to lay their eggs? Maybe they do this so they can complete their lifecycle and evolve into Octillerys?
But, yeah- I think that's generally what Swarms are supposed to be: Migrations whether seasonal or for breeding or whatever.
