The Biskit Twins, Whittany and Brittany, are the main antagonists of the series. They are bullies and all around rich mean girls that seem to envy Blythe. Though not the smartest, this duo is not opposed to using whatever evil scheme they can come up with (and "Daddy's" money) to sabotage Blythe and her friends' endeavors. Whittany and Brittany's father is the owner of Largest Ever Pet Shop, the unfriendly competitor of Littlest Pet Shop. Both the twins have red eyes; Whittany has black hair, while Brittany's is bleached white.
