Oh man, I'm sorry dude :( I was actually waiting to see if any swarms would show and just kept ending my months without doing anything about about 7 or whatever amount of months. And lo and behold a swarm :D At least for the second one anyways.
"Mezawari nandayo! Boku no menomae kara... kie noshimae! Majin Rengokusatsu!"
I've heard different stories about how people got their Eevee's. But I can't find one so I can't confirm any of them.
Some people have said they only appear in swarms. Others have said they are a rare appearance in Aurora, Pugilis, Viperia and Valora. Someone said that they were alerted to a 'rare spawn' in an area and it was an Eevee.
I can't find anything concrete though. :(
And then God created Saturn...and he liked it, so he put a ring on it.
