OK... Lemme walk you through it.
This was the first EBX Piggy I bought, got another one MOC for the collection. With the help of my brother we switched her head with that of the first regular S1 Miss Piggy figure. So now, the S1 Miss Piggy in my collection's display has the purple dress and the long-haired head.
What we did next was paint over the dress and skirt and shoes a cherry red by using acrylic paint. A bit got into the slips of her feet in the shoes, we tried to clean it out as best as possible. That's the extent of it, not much work.
LMK if you're interested, if not I wish you luck.
