Kenneth

Kenneth is a fish that appeared in a live action segment of the Super Mario Bros. Super Show!. It belonged to Mrs. Periwinkle.

Mrs. Periwinkle put Mario and Luigi to take care of Kenneth. However, Mario gave him a meatball for food, and the next second, Kenneth had died. Mario and Luigi were both worried about what happened to him, and what they were going to tell Mrs. Periwinkle.

However luckily, the brothers found another goldfish, and gave it to Mrs. Periwinkle, making her think it was Kenneth.
