This is an old Wacky today, going back to 1973 (ahh, that has a nice ring to it). Believe it or not, I bought this one for next to nothing at a garage sale a couple years ago. It was the only one there, and the only one I've ever found out in the wilds. Not in mint condition, but how fun to find an old Wacky I didn't have!
In case you've been under water since the 60s, this is a take-off of Kool-Aid drink mix. "Hey, Kool-Aid!"
