Incidental 24 is one of the show's background characters. He is a muscular goldfish, usually seen hanging out at Goo Lagoon, where he first appears in the episode "Ripped Pants."
He is very muscular. He is a bronze-brown colored fish with dark salmon colored lips. In later episodes, his dorsal fin is also dark salmon, while in earlier seasons, his dorsal fin is the bronze-brown as his body. He is orange in "Welcome to the Bikini Bottom Triangle." A blue version of Incidental 24 can be seen in the level "Krusty Krab Alley" in the game Super Brawl 3.
