Pilar is common grey fish, that is best friends with Nat Peterson. He is tall, with unmatching fins that are small like Evelyn's. He appeared in "The Inmates of Summer" at Inferno Island as a prisoner, where he earned the distinctive nickname "Bruiser" and used SpongeBob's play to jail-break, though the plan did not succeed. Pilar and Nat made fun of SpongeBob's wig in "Wigstruck," where he asked where he could get one (sarcastically). Pilar was arrested by "ManBob and PatBoy" (SpongeBob and Patrick) because he had untied shoes in Shuffleboarding. Pilar also makes a cameo in "Hello Bikini Bottom" during the first song where he asked Squidward for an autograph.
He is gray fish in blue pants with black belt, and booted in brown boots.
