The Angler Fish lives in Rock Bottom and first appears in the episode "Rock Bottom." He does not usually talk with a Rock Bottom accent, although he is heard blowing raspberries with his tongue. In the end of "Rock Bottom," when SpongeBob tries to thank him while blowing raspberries, he responds by saying, "You're welcome!" without the accent.
He is dark red and has a "stalk" on his head with a red orb on the top, which glows. He wears a purple bow tie. He has three dark red spots on both sides of his head, he has a pink fin, he has red eyes, and he has large dark purple lips, with a normal pink tongue. He looks much more normal in comparison with the other Rock Bottomites.
Role in series
After getting off the bus, he helps SpongeBob by chasing after his glove balloon and returning it to him, after which he inflates SpongeBob's balloon to float back to Bikini Bottom. SpongeBob says "Thank you!" in the tongue accent, but the Angler Fish responds by saying "You're welcome!" in a normal accent, much to the surprise of SpongeBob.
He is one of the Rock Bottomites that appear when Squidward is delivering food to 237 Rock Bottom. When Squidward, scared of the Rock Bottomites, calls the Rock Bottomites monsters, SpongeBob corrects him, saying that they're his friends. The angler fish then asks SpongeBob "what's up," before he and the other Rock Bottomites put on party hats and blow raspberries.
