MUMBAI: US broadcaster Nickelodeon has announced an online interactive initiative for its comedy/adventure series Avatar: The Last Airbender.

A new episode Avatar: Secret of the Fire Nation airs on 15 September. The story revolves around Aang and his friends, who are prevented from taking the easy route into Ba Sing Se while escorting a family of refugees and are faced with the challenge of making their way through the deadly Serpent's Pass. Along the way, Aang discovers a secret Fire Nation invention heading straight for Ba Sing Se and must stop it before it destroys the great wall that protects the city from invasion.

Fans who are looking for an interactive "Avatar" experience can log onto the "Avatar Secret Scene Creator" on www.nick.com. Here they will find the tools they need to create an original character and animate it, producing their own "Avatar" scenario.

Nickelodeon will randomly select ten scenes from the online game, record the dialogue with the actual "Avatar" voice actors and feature the completed scenes on Nickelodeon television as on-air interstitials. More than 100,000 scenes have been created and submitted to date. The Secret Scenes Creator is just one part of a larger online initiative for "Avatar."

In July, a new enhanced "Avatar" supersite launched on Nick.com, which provides fans with the content they crave for, like the details on the environment, games, videos,
character profiles and more. Launched in February 2005 Avatar is currently in its second season.
