Jojo Watterson, more commonly known as Granny Jojo, is a minor character in The Amazing World of Gumball. She is the mother of Richard Watterson. Gumball strongly dislikes being kissed by her. She is 63.
Granny Jojo is a pink rabbit, like Richard and Anais. She wears cat's-eye glasses with purple lenses, and a beige polka-dotted dress in Season 1, but just a beige dress in Season 2 onwards. Being an old woman, she has wrinkled lips, and crow's feet on the skin around her eyes (though her crow's feet could just be eyelashes).
In Season 2, she is shorter, has extra facial features, shorter whiskers, a brown dress, and an overall grouchier appearance, implying she has aged further.
Granny Jojo has a grouchy and somewhat lazy personality. As stated by Nicole, all she has left in her old age are cop shows, and kissing her grandchildren, mainly the former. She is very dedicated to receiving kisses from them, even to the point of forcing Gumball into one with a kiss on the lips. She also tends to spend her days watching TV.
She also does not seem to respect her grandchildren whatsoever, calling Darwin "fish kid" and/or "walking fish," and Gumball "the blue one," but she might have respect for Anais, as she calls her by her real name. Additionally, she forced Anais to carry her heavy bags upstairs for her, which, apparently, took an entire day to accomplish.
When she was younger, she still possessed her grouchy and uncaring personality, to the point of telling her young son, Richard, that magic is all fake; this shocked him into screaming loudly for fifteen straight years.
Her parenting style involves completely sheltering her kids, or "stopping problems before they happen" in her words. She scares the kids into doing nothing other than sitting on the couch, eating snacks she prepared, and never letting them think for themselves to the point where they can barely think at all, which resulted in much of her son's lack of common sense. The difference between hers and Nicole's parenting styles leads to a major conflict between the two mothers in "The Authority."
