Callie is very cheerful and excitable, and usually sports a grin on her face. She values her bond with her cousin Marie. When by herself, however, Callie can become upset and prone to overthinking. She is rather fond of puns and uses them from time. She liked activities. She has expressed a fear of heights, ghosts, skateboarding, and even Bluefin Depot. She easily becomes motion sick, and cannot ride a bicycle or drive, which is ironic. Easily distracted by cute, pretty, or striking things.
