Fishbones are skeleton fish that are found in the Mario series. They first appeared in Super Mario World and would later appear in later titles. They will swim slow in a straight line before swimming quicker when Mario draws closer. They can only be defeated by Cape Mario or Cape Luigi's spin attack in Super Mario World.
 Game History
 Super Mario Series
 Super Mario World
 Super Mario Galaxy
They could be found on the Bonefin Galaxy in Super Mario Galaxy during the boss battle with Kingfin. They would have glowing red eyes and attack similar to a Torpedo Ted. They home in on Mario and will try to hit Mario. After Kingfin has taken damage from Mario, he will summon more Fishbones, which will attack the player until Kingfin is defeated, in which they will disappear.
 New Super Mario Bros. Wii
They would appear in water levels in New Super Mario Bros. Wii. When they spot one of the characters, they will lock onto them and launch themselves at the players position. If they miss, they will crash and break apart like a Dry Bone. But unlike the Dry Bone, they won't get back together after breaking apart. They can also be defeated by running into another Fishbone. During dark cavern levels, their eyes will light up the area around them. In this game, they are called the Wet Bones by the Prima game guide. During the battle with Wendy O. Koopa in World 4, they can be seen swimming in the water tank in the background.
