Top Half: Kirby's honest. What more could you want?
Bottom Half: Remember, Karby doesn't speak. How else would you tell someone that you're at the bottom of a deep hole?
Kible: Actually, yes!
That's what I expect him to say, then have Karby fly up from nowhere.
Bottom Half:Yea,we know. yadda yadda yadda. Hey,did you know among the fans,Karby is one of the most well known?
It's the whole silent character thing, people can connect with them better. Like Red, the only Pokemon player character to never have a spoken line of dialogue in all the generations (as of now, since, ya know, Gen-V isn't out in America yet) so people feel most connected to him.
Red doesn't appear in Generation V. And I'm not sure the playable characters have any lines of dialogue if you didn't pick them, because they only appear in ONE place, AFTER you beaten the main storyline.
