Yeah, I really like her design as well. Seems like a pretty complex character model. Just the face alone looks rather complex. Great color scheme, too really dig the gold line running through the turquoise blue hair. Her pearl necklace has a grand moon, so she's clearly a major boss. I wonder if you fight her by capturing her chomp and snapping it back at her (as we've seen Mario do with a regular chomp to break a wall). I also wonder what wedding-related item the Broodals are looking for in the Cascade Kingdom?
Also, note the fashion similarity between this Broodal and Pauline. NPCs back in New Donk City did mention that many people try to ape Pauline's style...
