The Angler Fish lives in Rock Bottom and appears in the episode "Rock Bottom." He does not talk with a Rock Bottom accent, although he is heard blowing raspberries with his tongue. In the end, 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.
After getting off the bus, he helped 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.
