Rubella Deegan is Prunella's older sister. She is very spiritual and obsessed with psychic and paranormal phenomena. She is typically depicted as a mystic, and often talks in a very dramatic tone. She frequently chides Prunella and was first mentioned during a flashback in "Arthur Babysits," but made her first major appearance in "Misfortune Teller."

Physical appearance[]

Rubella is a poodle who is depicted with a tan complexion and curly orange hair that is longer than Prunella's, and wears a gold earring with an emerald in her right ear, a purple headband, a white blouse with fringes at the ends of the sleeves, a black and gray sleeveless jacket with flowers, two pairs of green necklaces, purple bell bottom pants, a belt buckle, and brown sandals and white socks. During a flashback/fantasy in "Arthur Babysits," her hair was shown to be brown; although when she was properly introduced in "Misfortune Teller," her hair was orange and remained so in her later appearances.
