Pokemon Mystery Dungeon: Dreamwalker

Nona is a human turned Mudkip, who finds herself lost in a world where her kind is only that of a whisper. Along with her two newest and only friends, it's up to her to unravel the mysterious plague that's gripped her new home, confront the shadows that stalk the edge of her dreams, and find out just why she was brought to this world- and just who wants her dead and gone from it.
