The Angler fish is a minor character in the series; he only appears in the episode "Rock Bottom." The angler fish helps SpongeBob get back to Bikini Bottom by tying SpongeBob's balloon to his wrist. Originally, the angler fish blew raspberries like all other Rock Bottomites, but he didn't actually speak until the very end of the episode.
The angler fish is red with a bright red aurora surrounding him, like all angler fish he has a bright light above his head to attract prey, which is also glowing red. The angler fish's mouth is purple and he wears a small bow tie that is also purple, his eyes as well are red.
