Reach waaay back into your memory banks for this one. Who remembers Burple?
My memories of it are really dim, but it was a Kool-Aid like drink that came in a squeezy, accordion-like container.
Retroland has some great memories of it, and says it only came in grape (purple Burple!) and orange flavors, which seems pretty limiting right there. (Wikipedia says it also had cherry and strawberry, which seems right.) Check out this commercial. Who remembers it now?
