Angelina has a soft English-accented voice. Her catchphrase is "Absolutely-Positively!" Despite her positive attributes, Angelina is something of a drama queen, and has had several crying tantrums throughout the series. However, she puts these aside in crises where the interest of her friends is concerned and comes to their aid, even occasionally saving the lives of those in mortal danger. For example, she briefly put aside her rivalry with the Pinkpaws twins when she saw them struggling to stay afloat in a raging stream, giving up her chance to win a tandem race to save them from drowning.
