I have been searching for a while now, but I still couldn't find a Petitmon, the Digimon I am longing for. I have also unlocked searched many places in my map, but I could not find anything. WHERE DO YOU FIND PETITMON???!!!
As per the same question in the Evolutions FAQ topic and the other Where can I find Petitmon? topic at http://boards.gamefaqs.com/gfaqs/genmessage.php?board=943756&topic=41862138, according to http://gamesxcap.web.fc2.com/digimonmap8.html, it shows up in the fall on evenings rarely in the final hunting map, Linker Ruins, which you get after beating the Championship. The other way is to hunt an Otamamon in NuruNuru Swamp and turn it back into an egg.
I just got a Otamamon, and I have already reverted it several times and got all of Dracomon's forms, but Otamamon can be hard to find especailly if you aren't sure you are looking in the right area. But thats how I got the sprites for my avatar over at WTW http://i47.photobucket.com/albums/f189/MasterElement/My%20Avatar/Slayerdramon.gif
