Sour Skulls Gummies by Candy People USA are a 4 oz. bag of sour fruit flavored gummy candy skulls inspired by Lördagsgodis or “Saturday’s candies.” Each Saturday, children are allowed to eat as much candy as they want. Swedes enjoy all types of candy on this day, especially tart, sugary goodness like the Sour Skull. Of course, the tradition is not only for children. Adults join in too because — who wouldn’t want to indulge in delicious candy every Saturday?
