| Mrs. Jötunheim
| Character Information
Mrs. Jötunheim is a short, elderly-looking woman. Her skin is green and wrinkled, and her grey hair is held up in a bun. She has a large, lavender nose and slightly pale lips with two blunt teeth sticking up out of the bottom. She wears a purple dress and two rows of golden bangles on both of her arms. She is shown to very short in stature, as both Gumball and Darwin are taller than her. She has white hair that is ungroomed.
Mrs. Jötunheim is very protective of her son, choosing what movies he should watch and what comics he should read, but it is revealed that she has a very good reason for doing so, since a giant's emotions are as big as their bodies and they must be kept calm.
- She makes her second appearance in "The Castle", as one of the guests who attend the party at the Watterson's House.
- Her design is a homage to the character Yubaba from the Japanese film Spirited Away.
- Mrs. Jötunheim is voiced by the same person who voices Granny Jojo and voiced Miss Simian on season 1.
- Her right eye is gray, indicating that she may be blind in that eye or have a glass eye.
- In Norse Mythology, Jötunheimr is the homeland of the giants, which is fitting because of who and what her son is.
