Rowlin is a character making her only appearance in the episode A Novel Approach in Kirby: Right Back at Ya!. Her name is a reference to J.K. Rowling, the author of the Harry Potter novels. She is a famous author who appears to be the same species as Tiff and her family are. Kirby and his friends first meet her when she arrives in Cappy Town, though this turns out to be a disguise that a monster known as the Broom King is using so he can kill Kirby.
Rowlin, like her basis, is a famous author, and Tiff is one of her fans. She writes books, such as her own series, "Pappy Pottery," to dream, which she reveals when the Broom King brings the Cappies under his control and forces them to attack Kirby and she arrives to stop the Demon Beast from creating havoc.
Rowlin is about half King Dedede's size. Her outfit consists of a green coat and a black dress. She has red glasses on top of her head and her skin is tan. Her shoes are orange.
