Dances of the kaguya.

Finger Bullet - With this jutsu, the Kaguya can fire there fingertip bones at an opponent like bullets.

Dance of the Camellia - The Kaguya can perform this jutsu by modifying the humerus (upper arm bone) of either his right or left arm to create a short, hiltless bone sword. Since he can increase and compress the density of his bones, he can make the sword harder than steel. He then uses the sword to fight; his style uses quick cuts and thrusts to disable opponents quickly. With Kaguya's formidable taijutsu skills, he can easily defeat a large number of people very quickly (as evidenced when he disposed of hundreds of Naruto's shadow clones without breaking a sweat). This dance also appears to be the most basic of the techniques related to his kekkei genkai, as it was unable to overcome an intoxicated Rock Lee, while his other techniques were easily capable of this feat.

Dance of the Willow - To perform this dance, Kaguya grows several long bone blades out of his body for use as weapons. Though they primarily uses two blades grown from the palms of his hands, he also uses several secondary bones grown from his elbows, knees, and shoulders. This dance form is incredibly acrobatic, using spins, charges, and long sweeping slashes to make the strikes more effective and to evade opponents' counterstrikes. Kaguya can also extend his bones to attack his opponents without having to adjust his own movement, a principle also used in his Dance of the Larch.

Dance of the Eightfold Vines - Kaguya pulls out two bone swords, and then dives onto the opponent, slashing twice. He then unleashes a flurry of stabs, knocking the opponent back. He then dashes behind the opponent, unleashing bone spikes all over his body and impaling the opponent.

Dance of the Larch - Kaguya uses this jutsu to create a mass of razor-sharp bone spikes all over his body. These spines appear to be branches off his preexisting skeletal structure rather than complete new bones. Kaguya is even able to grow these bones at an extremely rapid rate so they can stab an opponent even as they are growing. He can even use them to block or trap an opponent's strikes. In addition to being an unwelcome surprise for opponents, it makes him basically untouchable at close range.

Dance of the Clematis: Vine - Using his kekkei genkai, Kaguya can modify and pull out his own spinal column to use as a flexible chainstaff, regrowing a new spine to replace the removed one. The protrusions on the vertebra are modified to make them stronger and sharper

Dance of the Clematis: Flower - This is a follow-up to the Dance of the Clematis: Vine. Kaguya entire forearm is encased in a giant drill made of bone to attack the trapped victim. The bone is strengthened (through compression and its plaited spiral shape) to become the hardest type of bone the body can produce. The bone resembles a flower, hence the name.

Dance of the Seedling Fern - Kaguya's final dance, this jutsu causes a giant forest of bone spikes to burst from the ground. It is an extremely deadly technique; both Gaara and Rock Lee would have fallen to this technique if it weren't for Gaara's ability to use sand to levitate. Kaguya is able to emerge from any bone at will, giving him a deadly element of surprise this is a chunin level jutsus

There is no need to approve them, they are innate abilities for the Kaguya.
