Dance of the Seedling Fern

Countless bones rise from underground, which can be as many as thousands, up to the tens of thousands. The blades of bone indiscriminately slaughter whoever stands on the ground's surface. Furthermore, if this fails to bring down their foe, the user can become one with the bones, which in turn can allow them to attack an enemy unnoticed.

Trivia

 * Out of all the techniques shown through the Shikotsumyaku abilities, this dance is the only one that is ninjutsu, rather than a taijutsu.
 * After injecting himself with Kimimaro's DNA, Kabuto Yakushi gained the ability to use this technique through a doppelgänger of Kimimaro which emerges from the base of his navel snake.
