I'm not sure what would be the most fun here, but I can offer Frieda for either fairy tale shenanigans (she'll be the prince from The Little Mermaid) or snow competition activities (she may look weak, but she packs a punch)! Alternatively, I have Hijikata, but since you mentioned sending Rapunzel his way as the Gretel to his Hänsel, I didn't want to overload you with him... it's an option, though!!
