Three (as Captain Threemo, a parody of Captain Nemo in 20,000 Leagues under the Sea) uses his imagination with the other six monsters in a submarine while he is waiting for a submarine he ordered. Three speaks with a Cockney accent in this episode. He sounds a little bit like Roger Radcliffe and Skylar without his accent from Elena of Avalor.
