Betty is a young little diver who loves to be submerged in water! She always wears her pink and purple one-piece swimsuit, her black wetsuit, her pink swimming goggles, her green dive gloves, her red swimming cap, her gray fins, her orange snorkel, her flamingo pink scuba regulator and her teal water-tutu. She attends a huge all-girls diver boarding school (it's not located in the ocean) and she has nine other diver girls in her class.
