An old ref, but the design hasn't been changed. Just the info needs to be updated

Puff was made around either March or April, and got a child design in May. She's the youngest of Katakuri's kids, and the most spoiled, but all she wants is to be like her dad. She even picked up his eating habits and eats donuts with him.

The scarf around her body is his first scarf that got damaged, then given to her once he found a replacement. There's never a time where she's seen without it.
