In 1971 Pillsbury launched a line of four Funny Face walker toys (Goofy Grape, Choo Choo Cherry, Jolly Olly Orange and Rootin’ Tootin’ Raspberry).
Pillsbury employed a unique redemption strategy. They offered the walkers for free. All you had to do was send in 7 sugar-sweetened or 14 regular packages of Funny Face drink mix.
If you didn’t want to wait the time it would take to drink all that Funny Face you could pay 25¢ and only 3 sugar-sweetened or 6 regular packages instead.
