This is Jett's youngest sister, 6 year-old Lisa Herrera. She may look cute and adorable but she's always scheming with some sort of plan that Izzy has to try to get her out of.

Lisa is determined to track down her big brother and bring him home with her, but being 6, she'll need some help along the way.

Lisa almost resembles Jett completely except for her lack of stripes, and her feline-like tail.
