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 their spectacular underwater world. / Joining Olly and Beth are Skid, Doug's sleek transport vehicle, Brandt, a cantankerous hermit crab who imagines himself as a pirate, UMA, an eight-appendaged Underwater Maintenance Assistant, Ranger, a tiny cowboy seahorse who wrangles his herd of squid, Shankley, the Scottish sea crane who spins tales of the deep seas, Suzy, the awesome aerobatic seas plane, and Luseal, the fun-loving, athletic seal. / Whether carrying out a research assignment for Diver Doug, playing in spectacular Lava Rock Park, or evading the dangers found in Dark Trench, there's never a dull moment in Olly's world.
