The official drink of Slimer, Ecto Cooler is a glorious Hi-C juice that came in a large can or juicebox back in the days when Ray, Egon, Venkman and that black dude weren't afraid of no ghosts! It was green so as one could simulate drinking slime, or more appropriately ectoplasm.
Yo Jimmy, my mom forgot to pack me a lunch and I see that you got two delicious Ecto Cooler juiceboxes in your Thundercats lunchbox. May I have one?
