Originally developed for spying activities, this technique can be done after some surgery and actual body modification. The user dislocates their joints then controls their softened body with chakra, allowing them to stretch and twist any part of their body at any angle, elongating and even coiling around their opponent. This can also be used to make the user's body more malleable and snakelike. Orochimaru's version allows him to stretch any of his body parts well beyond their normal length and allows him to move in the manner of a snake.
