==_______________________Aviva___________________________== Aviva is a twenty-something-year-old scientist who lives in the Tortuga HQ. She makes the creature power discs. She can be a little bossy sometimes, but otherwise she is sweet and innocent. You may know she went to science camp with Zach Varmitech. ('Mystery of the Weird Looking Walrus)' She also is in and intense rivalry with Zach in inventing, as shown is "Cheetah Racer". Also she is my favorite character on Wild Kratts. I am done with this, so get used to it. (Sorry about that, but I can be sensitive, so sorry).
