I'm down for a Spinnerella in MOTUC. She seems like a perfect character to get into this line just due to the prestige of her being rare and expensive aka hard to get. Kinda like the Wun-Dar of PoP.
Dunno how they would pull her off with all the fabric she would need. Would that fabric look as good if it was done in plastic?
Regardless, I'd buy her for sure. She's near the top of the PoPs imo. ;)
