They feature vitamins in the shapes of the Flintstones characters: Fred Flintstone, Wilma Flintstone, Pebbles Flintstone, Barney Rubble, Betty Rubble, Bamm-Bamm Rubble, Dino, and The Great Gazoo.
For over twenty years, Betty was not included as one of the vitamins. However, 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 !fuckcars@lemmy.world people should be using Betty as their mascot.
