What, the plot I came up with? Most of it is a blur, but from what I remember, to quote the High Priestess, "I feel as though a terrible evil is upon our peaceful world once more."
It was like, a nightmare consumes the everyone's dreams. So Klonoa has to travel to many different dream worlds from his past (maybe some new ones too) and free them from the nightmares. I remember the twist in the story being that the main antagonist was going to be Klonoa's father (I don't know, I was 13 and dumb, alright?), and would die by his son's hand. I remember I'd named a few characters from the Klonoa 3 trailer (the one that recently got English subtitles). Like Kaze, his name is (according to the trailer) Passhu. The little girl with the patch arms that I called Inafa, the trailer calls "Woman". Also, I remember now, the name of the main antagonist was Pyros or Pyronis or some fire-related pun name.
I dunno, I always enjoy finding legitimate was to make a light-hearted series darker without going beyond the foundation set by the game, i.e. I wrote a fan-fiction (oh jeez here be go) for one of my favorite games (you know, besides Klonoa.), that game being Animal Crossing New Leaf, and the story sticks to the foundation of Animal Crossing, it's still mostly kid-friendly, but it has a more mature atmosphere in it (NO, not mature as in doin' it, mature as in how should you react to the death of someone you care about.).
