Fruit Brute?

You should know the three monsters that may have made it to your table in the morning; Count Chocula, Frankenberry and Boo Berry. But what about a werewolf? Introduced in 1975 Fruit Brute made its appearance. In the commercials the werewolf would howl "Frooooooot" (you can stop howling now). Unfortunately, the cereal was discontinued in 1983.
