From Avatar the Legend of Korra :

The Future Industries Fire Ferrets, also known as simply the Fire Ferrets, are a pro-bending team formerly consisting of Mako the team's
captain and the firebender of the group, Bolin, his earthbending brother, and Avatar Korra, the team's waterbender. Together they competed
in the Pro-bending Tournament in the hopes of winning the championship prize money. The team's mascot is Pabu, Bolin's pet fire ferret. Currently,
the team consists of Bolin and two new teammates, as Mako and Korra have left the team.
