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.
