When was Wacky Blackout created?

There is no widely known or documented product or game called "Wacky Blackout".

Could you please provide more information or context? For example:

* What kind of product is it? (A game? A toy? A drink? Something else?)

* Where did you hear about it? (A store, online, a friend?)

* What makes it "wacky"?

With more information, I might be able to help you find the answer!
