The pirate crew includes Dandy, the apparent leader; Dyle, who is motivated by riches; the task-focused Astro; the agreeable Sprout; the pensive Vee; the curious Shelly; the concerned Bobette; the uncertain Bassie; the enthusiastic Gourdy; and Pebble, their dog. The mermaid faction includes a large cast: Finn, Shrimpo, Brightney, Blot, Yatta, Looey, Boxten, Poppy, Scraps, Goob, Flutter, Connie, Glisten, Rodger, Gigi, Toodles, Teagan, Razzle & Dazzle, Tisha, Brusha, Rudie, Ginger, Coal, Eggson, Flyte, Cocoa, Rebecca, Soulvester, and Eclipse.
