Which character is missing from "The Flinstones" Chewable Vitamins?

Although the Flintstones Chewable Vitamins did not originally include the character Betty, she was added to the line-up in 1995. Since that time, all of the major Flintstones characters have been represented by the chewable vitamins.

Flintstones Chewable Vitamins include chewable fruit-flavored tablets in the shapes of the following Flintstones characters: Fred, Wilma and Pebbles Flintstone; Barney, Betty and Bamm-Bamm Rubble; The Great Gazoo; and Dino. For the first 20 years of production, Betty was not included in the line-up of characters represented by the vitamins, but she was added in 1995 following a campaign by fans of The Flintstones, replacing the Flintmobile vitamin tablet.
