Well, yeah there are many ships, but, what i go with, is, well always what's official, and this is, well that, but...  Would y'all like them to get more involved in love stories or something? (embarassed) What do y'all think?

It would be interesting to see if, in any future sequel, how that would play in the story, yeah.

[Rupurudu!]

Klonoa is a dream traveller and Lunatea is one of the places he visited in his dreams. Since he doesn't stay in the same dream, he can't stay with lolo forever. Because of that, it wouldn't make sense to progress further in their relationship.

Yeah, but i'm mostly talking about spin offs, and besides, every game other than DtP and L'sV, kinda ignore that, so you get Hewpoe twice again, and, Lolo again, all that stuff.

[Cobra!]

Maybe he can revisit dreams. It would make sense for Phantomile or Lunatea to be in trouble again and Klonoa needs to return to save them again? People have recurring dreams, right?

Not a bad idea, but as far as I know they are a bit young for that.
Google search (yeah, I know. not very reliable) suggests they are both around 12-13.
Although as Rupurudu! pointed out, Klonoa is a (the) Dream Traveler, and is shown to have little to no control over who's dream he goes to or for how long so a deeper relationship with Lolo would be nigh impossible, but Noctis Soul and it's successor, Dream Crusaders, does showcase Klonoa crossing between Dream Worlds...

I always thought those were his dreams, well...

Again, i guess people only care for DtP and L'sV, characters re-appear in other games, even if it is a shattering build up the end of DtP and L'sV, only to get to here, well i guess that's just how it is...
