Mariella Lorraine is the mother of Helen and Jake, the sister of Jorge, the aunt of Carolina and the wife of Daniel Lorraine. She is bilingual, as she can speak both English and Spanish, also indicating that she is probably from Mexico. She also works in a garden shop.
- It is unknown who her parents are. Even when Helen draws her family tree in Martha's Pack, she did not draw them.
- Despite all the Lorraines (as well as T.D. and Martha) hating Mushy Duck, she seems to hate it the most. Also, despite her claiming in the episode that she kept involuntarily humming the theme tune, she was never actually heard humming it.
- Martha sometimes refers to her as her mother, in spite of the fact that she clearly is not Martha's Mother.
Mariella usually is seen wearing a purple shirt, gold hoop earrings, a red flowered skirt, and pink flat shoes. She has brown hair which she usually keeps in a ponytail.
In the summer, she wears a beige t-shirt, green shorts and sandals. In the winter, she wears an aqua coat, pink gloves, grey snow boots and purple trousers. She generally wears a purple nightgown to bed.
