Tina and Tia is the relationship between Tina Taylor-Cannon and her younger sister, Tia Taylor.
When both sisters participate on being in the T.V. show, C.C. Cruiser and the Hot Rod Squad, Tina got the main role as the hot, yet smart scientist, while Tia ends up being the studio's garbage woman. Jealous of her older sister's success, Tia vows to get a more fair career by humiliating her sister on stage. She "modified" the stage to make it look "better", but that didn't go according to plan as one of her traps nearly got the car Rodd to explode and Tina and her husband Cash along with it. So, Tia, with some help from Sally, quickly deactivated her traps and Tia confessed her sadistic actions. And just when she was about to depart from her job, the director stops her, impressed by her intelligence into building her own personal traps on stage, and promised Tia she can be the new stage manager and play the role as a villain in the show, as long as she used those traps for good. Tia delightfully agrees and apologizes to her sister for almost blowing her up. Tina quickly forgives her and they had a more mellow sisterly bond from then on.
