Dry Bowser

Bower Bones is the Dry Bones-esque form of Bowser in New Super Mario Bros. When Mario confronts Bowser at the end of World 1's Castle, Bowser is dropped in a pit of lava like in the original Super Mario Bros. Instead of dissappearing off screen, Bowser briefly appears with his flesh burning off. Following this, Bowser Jr. takes his father's remains.

Much later, in World 8's Castle, Mario fights him. Bowser Bones fights similar to Bowser, except he throws bones like Bowser threw hammers in Super Mario Bros. He is invulnerable to most attacks, including fireballs. Shell Mario can defeat him by sliding into him at full speed, and Mega Mario can defeat by simply stomping on him.

After the Castle, a bridge appears to another section of World 8. After this, the Bowser Castle is located. At the end of this castle, Bowser Jr. throws Bowser's bones into a magic pot and Bowser is revived, leading to a final confrontation between Mario and the Koopas.
