Step 1 : Introduction to the question "Which character was originally left out of the Flintstones Chewable Vitamins?"
Flintstones Chewable Vitamins are supplemental multivitamins for children based on the animated sitcom The Flintstones. For over 20 years, Betty was not included as one of the vitamins. Some say it was because a mold for Betty looked too much like Wilma, while others claimed Betty's small waist meant the individual vitamin tablets kept breaking. After a grassroots campaign and the results of a Bayer telephone poll came in favor of including Betty, the character was added to the lineup in 1995, replacing the Flintstone car. The rock band “Betty's Not a Vitamin” was named in honor of the “controversy”.
