Hi-C's Ecto Cooler Is Officially Coming Back For 'Ghostbusters'

The return of "Ghostbusters" this summer wouldn't be as nostalgically complete without the return of two of the franchise's biggest stars:

Slimer -- he's officially in the trailer -- and his favorite juicebox, Hi-C's Ecto Cooler, the green citrus drink that haunted the lunch boxes of every kid in a U.S. elementary school in the late '80s and '90s.

After months of online rumors, we can officially report that Ecto Cooler will hit grocery store shelves on May 30 as a tie-in to this summer's "Ghostbusters" reboot, which hits theaters on July 15 (with a new website, social media presence and decidedly Slimer-less packaging -- see below).

"Hi-C Ecto Cooler fueled a pop culture phenomenon that is well remembered and beloved by fans to this day,” Charles Torrey, the vice president of Minute Maid/Hi-C Brands at Coca-Cola North America, said in a statement. “Sony Pictures was extremely enthusiastic about bringing it back for this special occasion, and the timing of the upcoming Ghostbusters film made this the exact right time."

For a while, it seemed like Ecto Cooler was really the only Hi-C flavor anybody drank (or remembers drinking) in the '80s and '90s. It was created in 1987 to promote the "Ghostbusters" franchise (especially the cartoon), and stayed around until 2001, long after "The Real Ghostbusters" went off the air.

But Ecto Cooler was eventually rebranded into other flavors and discontinued altogether, much to the dismay of a few nostalgic consumers.

If you are such a fan and can't wait until May 30, Coca-Cola is hosting a sweepstakes on social media for a chance to win a 10-pack of juice boxes from the first run of the relaunched Ecto Cooler.
