a swarm is a group of Pokemon that appear on a random route after recieveing the national dex. to find out where the swarm is and what Pokemon are in the swarm, go to dawn/lucas's house in sandgem and talk to their little sister.
it is a swarm Pokemon on route 206
once you get the national dex Pokemon will swarm and it will swarm north of the fight aerea
Theres a swarm at the valley windworks.
They swarm occasionally on route 224
Lots of Pokemon
the swarm Pokemon are Pokemon from a different reigon who come and swarm a certain place. for example, skitty aren't usually found near sunnyshore city, unless they are swarming that day. hope this helped!:D
You can't get the Pokemon in Pokemon Platinum.
its a swarm, you have to check dawns house everyday. talk to her sister and she will tell you where the daily swarm is.
you can find them in route 206 only by swarm though if you don't know what a swarm is then go back and talk to dawn/lucas sister and she tell you there is a swarm on a route she tells you the route and the Pokemon swarming there
You also need to beat the Elite 4 before the swarms activate.
You cant get a shiny eevee on Pokemon platinum unless you have some sort of cheets. NOT TRUE... get a shiny eevee if its the swarm of the day and then just chain them..
i don't know but it can be caught by swarm (talk to dawn/lucas' lil sister to find out what swarm it is, it changes daily)
