Grenda is Mabel and Candy's best friend, notable for her large physique, obsession with boys, great physical strength, and deep, gruff, and masculine voice. Grenda is insecure about her low, gruff voice and is constantly belittled, as well as made to feel weird and out of place by popular girls such as Pacifica Northwest. This tends to make her uncomfortable, sad, and angry. She's very supportive of her friends and while with them is usually happy. She, like the rest of her friends, likes to talk about boys.
