Kilgore is a violet pre-named ultravore that is occasionally available for purchase in The Fish Emporium for 50,000 shells. Like other ultravores, Kilgore eats carnivores and drops bags of shells but also has the special ability to play music but the famous composer Richard Wagner.
Kilgore is known to begin playing Ride of The Valkyries when it is hungry and makes the same slurping sound when eating as other voracious fish do, however, it will not roar unless it is singing a tune. In this case, it will interrupt it's own performance to roar.
Unlike all other musical geniuses, Kilgore in incapable singing multiple songs. Additionally, the only song it does know will be an extended version every time and will not get an applause when it ends. He is the only fish that can sing the extended version of Wagner's song, which is 1:28 long.
