Originally Marmalade had been chosen by Cherry Jam until realizing that she wouldn't make a very good singing partner.
Marmalade is a girl, despite claims of being a boy in earlier episodes. She has bright orange-brown fur and long ears resembling red-orange hair, almost like Hana but more ear-like. It's eyes and nose are dark brown in color. Along her body, it has small bright orange markings. Her collar is peach in collar, that gains daisy ornaments after Orange adopts her, to match the one's worn on her ears.
