Lenny is a blue anchovy who has appeared in many episodes. He first appears in Help Wanted, in multiple anchovies. His name was revealed in the episode, "Good Ol' Whatshisname." Lenny is married to Mable and they had two children from Born to Be Wild. He makes two cameo appearances in SquidBob TentaclePants. Lenny is also seen in SpongeBob SquarePants: The Yellow Avenger as one of the Fish harassed by Little Dirty Bubbles.
He wears a tuxedo every time he is with Mable. Sometimes he wears a white shirt. However, in Spongicus Lenny's tuxedo was shown without his head and his other look was there so it could possibly be that the other one is not Lenny or neither it was another fish because the tuxedo was only shown, not his head.
