|
Old Man Jenkins, also known as Incidental 86[1], is an incidental character who first appears in the episode "Mermaid Man and Barnacle Boy." He is likely classified as an elderly-type incidental.
Description[]

Evolution of Old Man Jenkins' default design.
He is a big yellow elderly fish with light orange liver spots, purplish-red veins on his neck, and stubble on the top of his head and on his chin. He wears a teal hospital gown with a white tied up collar and rides in a bamboo wheelchair with red wheels. In his older appearances, he was light blue and the veins on his neck were black. He also wore a lime green turtleneck sweater with a dark teal collar and his wheelchair had green sides and his wheels were brown in the middle. The bamboo frames and the seashells near his feet also had black outlines instead of the default default brown outline for the frames and the default red outline for the shells.
