It wasn't one of my absolute favorites either, but I still thought it was good, and I have to give the developers some credit for trying something different. By the way, the final boss was Wart (who seems to have only made one appearance).
As for the question, uh.... I think I like both just as much (or in their own way). Forcing myself to choose, however, it's probably Kirby Yoshi.
I don’t think anyone should get married, lol. What’s the point of getting the government involved? Idk, it’s a lot of money and trouble to get a divorce. Just commit without all that hassle.
