Franken Berry is a member of the line of monster-themed breakfast cereals produced by General Mills for the North American market. It contains strawberry-flavoured corn cereal bits and marshmallows. Franken Berry is also the name of the cereal's mascot, a variant of Frankenstein's monster. In 1971, the first two cereals in the line were introduced, the still-available Count Chocula and (strawberry flavored) Franken Berry. Franken Berry was very popular at that time, even though the initial batches of the cereal used a dye that didn't break down in the body, causing many children's feces to be bright pink, a symptom sometimes referred to as 'Frankenberry Stool.' Franken Berry is sometimes mistakenly thought to be discontinued but in reality, its distribution is just much lower and more sporadic than that of the flagship cereal Count Chocula. The best time of the year to find Franken Berry is around Halloween.
