Korra begins her training with Tenzin. While training, she runs into great difficulties and becomes frustrated with her inability to learn Air Bending quickly. She also becomes more interested in ProBending, a sport where teams consisting of a Fire Bender, Water Bender and Earth Bender attempt to knock each other out of a ring, and sneaks out to see a match, against Tenzin's wishes. While there, Korra meets the Fire Ferrets, which consists of Mako, Bolin and Hasuke. When Hasuke fails to turn up for the final match that the Fire Ferrets need to win to enter the Tournament, Korra joins the team in his place.
