Answer: Hi-C Ecto Cooler

If you were a school-age child in the late 1980s, then there’s a pretty good chance that more than a few of your packed lunches contained a box of Hi-C’s Ecto Cooler. The neon green juice-box style drink was a rebranded version of an earlier drink from Hi-C called Citrus Cooler, courtesy of a deal by Minute Maid in 1987 as a tie-in for the cartoon series The Real Ghostbusters, based off the 1984 live-action film Ghostbusters.

The drink was so popular in the Hi-C lineup that Minute Maid continued to produce Ecto Coolers long after the 1991 cancellation of the cartoon series the drink had been rebranded to promote. Although Slimer, the green slimy sidekick from the cartoon, vanished off the boxes in 1997, the actual product name remained until 2001, at which point the neon green drink underwent a series of makeovers.

First, its name was changed to Shoutin’ Orange Tangergreen. Then, in 2006, it was once again rebranded as Crazy Citrus Cooler. Finally in 2007, a full 20 years after it was “introduced”, the ghostly goodness of Ecto Coolers was finally laid to rest for a time. To coincide with the 2016 reboot of Ghostbusters, Ecto Cooler was temporarily rereleased for a limited time as a promotional tie-in with the movie.
