Rocko nor Monica look straight up black to me. Im sure Rocko is not pure black, he is brown and I know Africans can be medium brown like him, but working with west Africans, where our ancestors came from, and looking at them, I can tell the difference. Moncia's father looks like the youngest son. From what I hear, her father is bi-raical and her grandmother is white, which would explain monica's some what mixed raced appearance, I have seen mixed girls that have looked like Monica before. Their eye color is recessive genes from her mixed race father, and their light complexion as well.
