Layla is a white cat appearing in Mario The Music Box remastered version. Layla has a similar appearance to Len's cat form, although she is not black, but white, and her eye coloring mirrors Len's. Her human form is shown to be also similar in appearance to Len's human form, the differences being that she has black hair instead of white, with her eye coloring remaining the same as her cat form. Layla, like Len, can willingly switch between her cat and human form. She is Len's twin.
