Yes, thanks to forum member and fellow Blue Arrow, KoolKorra for telling me about this.

NOTE/ If you are not from America you may need to use a program like Tunnelbear to play the game, Nick.com is region locked.
It is a tetris battle type game where you play as a chibi version of a nick character, including the TMNTs, Power Rangers, Korra, Aang and many other nick characters.
As you play you get to see little chibi animations as you either start to win or lose. It is not only about Avatar, but still fun to see more Chibi stuff.

Chibi Aang is locked when you first start the game, Beat story mode with Korra to unlock him.[/caption]
