She is an adventurous character with considerable talents. She often drags the dumbstruck Cavin (of whom she is more than a little fond of) in story situations. She also befriended the Gummi Bears in due time and is close friends with Sunni. She hates the pomp and circumstances with being royal while wishing to be more involved with the governance and defense of the realm. Consequently, she tends to be somewhat rebellious at times, often spurning her father's admonishment that "a princess must set an example for her kingdom". That, however, does not prevent her from exerting her authority as a princess whenever it suits her purpose. She even proves that she needs no protection, as she had surreptitiously (look it up) trained herself in the use of weapons.
◾Calla is not included in the official Disney Princess line-up or in any of the merchandise. This is most likely due to the fact that she is from a TV series, whereas all of the official Disney Princesses come from films.
