Olivia

The second oldest joey in the family of yellow-footed rock wallabies. She idolizes her older sister Lisa, and is her side-kick when it comes to mocking their little brother Joey.

Trivia
Olivia is the only character confirmed for a planned reprisal in The Serpent Curse 2. Status of other characters is yet to be revealed. "She will have a much larger role in the sequel, but still won't be the protagonist" stated Ryan "R-Gii" Wallace on the Serpent Curse wiki. "While she merely plays a minor role in the first, I think it will be fun to expand upon her character in the second."
