Ethel Rainicorn is the mother of Lady Rainicorn and the wife of Bob Rainicorn who appears in "Her Parents." She became quite excited upon meeting Jake for the first time. While Jake was impersonating a Rainicorn, she believed he was handsome and rich, and therefore a perfect match for her daughter. When she discovers that he is a dog, she becomes even more elated. She sympathizes with dogs as her husband Bob was saved by one during the Rainicorn-Dog Wars.
She is a female Rainicorn with a long body, longer than Lady's. She has horizontal stripes with rainbow colors, a white horn, light-blonde hair. She wears glasses with thick, round lenses due to poor vision. She also wears a Universal Translator.
