I got my hands on a new 8 inch Rainbowdash (£7.99) along with Princess Twilight from a store here in the U.K called Home Bargins; last Saturday.
I'm turning Rainbowdash into Foxy from Five Nights at Freddy's I'm keeping here hair and tail but going to be using a tube of Acrylic Crisom Red paint to paint her body. I think I'll be able to use the big tube for just two coats. I'll post a picture of it when it's done.
