Treetop Trouble is a flash game available on the Internet. It revolves around the first book of the Avatar: The Last Airbender, specifically the tenth episode, "Jet".
Sokka has escaped his captors, and is now in a race against time to save the village of Gaipan. He has to call upon all his warrior skills to navigate the precarious perches high in the treetops while dodging archers' arrows and staying ahead of Jet, who is hot on his trail in an attempt to stop him before he reaches the village.
In the episode, Jet was fighting against Katara and Aang.[1] In this game, however, he appeared from the vines trying to recapture Sokka.
Also, in the series, Jet never knew that Sokka had escaped, until he appeared atop Appa, announcing that he had warned all the villagers and helped them escaped.[1]
