"Dive Olly Dive!" follows the fun-fi lled underwater escapades of Olly and Beth, two young research submarines-in-training. The two live in a deep-sea research center known as SURF--the Special Underwater Research Facility, where they experience the joys and challenges of life in their underwater world, much in the same way that preschoolers experience life in their world. Under the guidance of their enthusiastic human teacher and mentor Deep Sea Diver Doug, Olly and Beth are training to one day become full-fl edged research submarines.
