Taffy is the blonde member of the group, renowned for her cry of "Zowie!" whenever she comes up with a plan (or "Another Daffy Taffy Plan" as Brenda and Cavey would call it) to catch the culprits.
In spite of her usually zany plans, Taffy is actually very capable and clever. She has the ability to sweet-talk Caveman into acting as bait for her plans to capture the culprit. She usually wears a green dress with matching shoes. It is revealed that Captain Caveman has a crush on her.
