Some of the other characters (such as the Fire Tug, Big Mickey, Mighty Mo, Pearl, the Shrimpers, and the Buoys) do make several appearances, but don't have any dialogue whilst some such as Sea Rogue's Uncle and the Pirates (a.k.a. The Green-Eyed Things) never made any appearances (although Sea Rogue's Uncle did appear as a cameo in the episode "Who Took My Crayons?", and one of the Pirates was shown in the place of Sea Rogue when he covered Lillie Lightship and a bell buoy with a blanket in the episode "Dream On").
