How do you swarm im Pokemon Pearl?

Answer 1

Okay, so swarm is when you talk to Dawn's little sister in Sandgem town. She will say : " What did the news say again?" then she says "oh yeah theres a whole bunch of ______ on route ______ " " You better hurry i want you to do better than my sister Dawn.

So basically she tells you about a swarm of pokemon on whichever route she tells you. The Pokemon change everyday when you talk to her so if you are looking for a certain pokemon during a swarm but it wan't the one you were hoping for, just save and change the time to 23:59 on your DS, after a minute passes talk to her again and she will mention a new pokemon :)

Most of the swarm pokemon are good :)

I managed to catch Absol, Pidgeot, Surskit and lots more thanks to this :)

Hope this helped :D
