Well, I agree on the Robin thing!
But I'm fine with Peach-napping! It just wouldn't be right without it! But that doesn't mean we need to change Peach's character just to do so. Sure, Peach was clueless in Sunshine, but if her voice actor changed her tone of voice into a different confused one, she wouldn't have been clueless at all even with the exact same line! (Saying "I'm your mama?" as in, "What are you talking about?") And I certainly don't see her as a glutton, rather a giving and kind person.
