Kenneth

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

One day Mrs. Periwinkle put Mario and Luigi to take care of Kenneth. However, Mario gave him a meatball, 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 fast, and gave it to Mrs. Periwinkle, making her think it was Kenneth.
