ImaginOcean "follows the undersea adventures of a group of fish friends, who uncover a treasure map that leads them to learn about themselves and ultimately uncover the treasure of each other's friendship." The production takes "audiences on a one hour magical underwater journey full of surprises and special effects. The seafaring stars Dorsel, Tank and Bubbles open an enchanted world of aquatic adventures where they meet jiving jellyfish, a strong-willed seahorse and a new friend, lovable Leonard the Octopus."
