She was born in a rich family who didn't have much time to her. Her older cousin Leon was her best friend at the time. Leon moved out and Andy had a hard time getting new friends. Andy met Zack and he started helping her with her studies, being her best friend. Andy parents died in an accident, the only other alive relative of her was Leon, who wans't exactly ready to raise a child. When Azule expressed interest in adopting Andy, Leon didn't think twice before letting it happen, as they sure would do a better job than Leon. Because of Azule's fragile health, Zack was the one who raised Andy. Once Azule died and Zack became the one legally responsible for Andy, they both moved to another city. There Andy had more luck with friendships and soon she had more friends than she could count in her both paws. She started to get more serious about her geology interest and started studying hard to make it her job when she growns up. One day Zack found a lost bumblebun called Blue and brought him home. Andy and Blue soon turned best friends, having a more of a big sister-little brother relationship.
