Debbie Thornberry

Debbie is a typical teenage girl who is Eliza's older sister, interested in music and fashion, and who longs for a normal suburban life though her parents' job deprives her of this. Despite being rough around the edges, she does care for Eliza. She commonly wears an orange camisole, a green jacket, blue jeans (with holes in them) and brown shoes. In "The Wild Thornberrys Movie," she learns Eliza's secret, but if she tells anyone she'll become a baboon. It is shown in the episode "Chew If by Sea" that Debbie suffers from chronic seasickness. Debbie is 16.
