LOS ANGELES — Though the first of three Avatar sequels won't unspool until 2017, here's good reason to believe that they are right around the corner: All of the film's social-media feeds, some of which have sat idle since 2011, are being re-launched this week.

Avatar feeds on Twitter, Tumblr, Pinterest, SoundCloud and Facebook started coming to life on Wednesday, just a couple of weeks after director James Cameron said he's delaying the release of the first of three sequels to give them time to finalize the script.

Mashable has all the details on the Avatar social team's plans, as sprawling and ambitious as a trip to Pandora itself:

Avatar on Twitter

The official Avatar Twitter feed — @OfficialAvatar — last tweeted on Feb. 3, 2011, celebrating Cameron and The Earth Day Network exceeding their goal of planting one million trees worldwide.

They're back! This time around, fans who engage with the account will earn custom badges and other rewards (like the one above) that they can display or retweet. Expect the account's 26,500 followers to grow like phosphorous weeds in the coming weeks.

Visuals, visuals, visuals — Tumblr will be the place for Pandora's rainbow-colored flora and fauna, along with some key moments from the film, at @Avatar.

Avatar on Insta — not just for Na'vi selfies and pictures of the juicy, delicious fruits of Pandora right before they're bitten into. Instead, Avatar will use Instagram for flashcards that facilitate Na’vi language learning.

Na’vi language creator Paul Frommer, a linguistics professor at the University of Southern California, helped with the @LearnNavi Instagram feed that will teach basics of the native tongue. Pairing words with stills and never-before-seen images from Avatar will allow fans to engage with the language in an all-new way.

The Avatar SoundCloud profile, @TheSoundsOfPandora, will work in conjunction with the Instagram account to teach fans how to pronounce Na’vi words. Expect some Na’vi music and natural sounds from Pandora, as well.

Avatar on Pinterest

Here's where you can find it all: The Avatar Pinterest page is set to become a "visual encyclopedia of Pandora," with images of creatures, plants and vistas that fans can download for their own use. @UltimateAvatar will also contain images from the Avatar Extended Collector’s Edition, and later let fans pick their favorite shot from the finished film.

The big one — with nearly 54 million fans and surely more to come, the Avatar Facebook page has remained active in the years since the first film's release, posting photos and news along the way.

Now it becomes a hub where content from all the aforementioned Avatar social channels can be found, with standalone posts and announcements.
