Fred is seen in quite a few episodes as a backup character or a person in the crowd who talks or is in an angry mob (seen in a few episodes). His name was revealed in "Patty Hype". He is voiced by Tom Kenny. Fred first appeared in Reef Blower. He is usually the most closest to Nancy in cameo-places where there's a lot of important fish. A running gag is that he gets injured many times and yells "My Leg!"
In the episode: Plankton!, he was blue colored. Fred also has many look-alikes in The Paper, The Chaperone, and others. At the KelpShake restaurant, he was annoyed by Mr. Krab's fake sneezing and saliva spitting.

He is also very eyeshot by King Neptune's very hot baldness in the Krusty Krab 2 in The SpongeBob SquarePants Movie.
