Dive Olly Dive! follows the adventures of Olly, a young submarine-in-training, and Beth, his best friend, and fellow sub-in-training. Stationed at the Special Underwater Research Facility (S.U.R.F.) under the guidance of Diver Doug, the young subs explore the underwater world.
This show provides examples of:
- Expository Theme Tune: Adventure begins in the sea / With Olly and Beth, you and me / We are happy and free / Come on, have fun in the sea / Come on and dive, Olly, dive!
