Christa is the youngest teenager in the house. She is artistic, excitable, a genius, and a heavy sleeper. She has long light blonde hair, gray eyes, and pale skin. Christa has a white tank top with blue polka-dots, a blue skirt with white polka-dots, white gloves, and blue shoes. She dresses with the same style as her mother and siblings.
Christa adores her mother, and even shares the same favorites, outfit, sign, appearance, and some traits with her. Her favorite color is turquoise, favorite food is key lime pie, and favorite music is classical, which she shares with her siblings and mother. She is romantically involved with another boy in the neighborhood named Finn Lucas.
Christa lives in Lunar Lakes, on 139 Avenue of the Asteroids. They live in a large, expensive house. She might be a descendant of the Landgraab dynasty, because she shares their last name.
