I was looking for a different password for Ragnarocks besides the alternative one,DRG_RGN. Since Ragnarocks is the first legend I used different first legends passwords' like eared mew, gobi, archreap, marinin, etc. One password they share is Pyrolias. Going all through the capitals and lowercase the password seemed good giving monsters like serket (1st legend) Devi (1st legend) and a locked one (legendary dog, probably white hound which is 1st). when I got to 6yrolias however the strangest thing happened, I got a pure dragon. This makes no sense becuase the dragon has a legend form, so why did I get a pure breed. Any idea why this happened?
