Franken Berry was brought to life in late 1971 by General Mills. It was the second Monster cereal General Mills produced. Due to the popularity of Monster movies since the 50's and 60's, it's believed that General Mills saw an opportunity to benefit from the monster phenomenon. Hence, the Monster cereals were born. Franken Berry is obviously styled after Frankenstein, but this gentle giant wouldn't hurt a fly. In fact, this most timid of the monster cereal characters would often get spooked very easily in the commercials.
