Bikini Bottomite

Bikini Bottomites are a species of sapient fish humanoids from a Nickelodeon TV show, SpongeBob SquarePants. They are omnivores that feed on the same food as many other sapient species, especially Krabby Patties, and unlike most fish, they can survive staying in fresh aii for an extremely longer length, due to their lungs being tolerant to both water and sea.
