Jinkies wasn't meant to be made, but nobody's complaining! Due to some shenanigans involving some black magic and untested science, Jennifer Adreana was accidentally fused with Inky Blotts. They eventually became their own person, which was a problem to their two halves. They decided to let Arthur split them, though, and in turn he cloned them. They now live their own life, considered the child of their two original halves. Though they are visually and mentally around 17, approximately, they're only a few years old.
