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
You can't get the Pokemon in Pokemon Platinum.
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 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
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 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)
