— Incidental 25, "Krusty Dogs"
Incidental 25 is a fish who first appears in "Boating School." His incidental type is currently unknown.
He is a skinny lime green cod with darker green fins. He wears a white cap with a life preserver symbol on the front, and a white polo shirt. He looks almost exactly like Incidental 26, with the only differences of being that his eyes and mouth are more closer together, his lips are circular, his legs are longer, and that he is thinner. In his older appearances, the sclera of his eyes were dark green. In his even older appearances, he had thin black feet. In some of his appearances he had the same facial appearance as Incidental 26, making it nearly impossible to tell which is which.
