Anchovies are a large group of fish that have varieties of looks but normally are skinny, expose at least half of their bodies, and have eyes on top of their heads. Some of them appear to go to Bikini Bottom High School, where they are loved by teenage girls. Known anchovies include a handsome anchovy named Billy Fishkins, a nerdy anchovy named Brian Flounder, and an over-rated anchovy named Octavius Rex, whom Pearl once dated and is nicknamed "Long, Tan and Handsome" even though the latter doesn't apply very well. They usually only say "meep", and rarely use English. Some of them are in the Jelly Spotters, where they annoy Kevin often by repeating a wəˈ sound in the episode I'm Your Biggest Fanatic. They debuted in Help Wanted, where they flooded and almost completely destroyed the Krusty Krab. They appear in Bikini Bottom often, as citizens, but appear in the episodes Help Wanted, The Play's the Thing, and Accidents Will Happen in large, ravenous groups that will stop at nothing. A Blue one is friends with Franco, and Harold Smith. They are known to attack if not pleased. They are often background characters, but in some episodes they have more major roles. Some of them like Krabby Patties.
The language of anchovies is very unique. They usually only say "meep", but in the episode I'm Your Biggest Fanatic they are able to say other things. They are loved around Bikini Bottom High School, but they cannot respond. It is shown that some anchovies are able talk normally. For example, Mable is an anchovy who is able to talk instead of saying "meep".
