Drinking milk was able to be used as a bonus action by Marrow in battle. Drinking different types of milk change the effect of the Hone-Hone no Mi. However only one Milk Ability is able to be used at once.

Milk Effects:

 * White Milk - Doubles Damage.
 * Chocolate Milk - Heals the user an unknown amount.
 * Strawberry Milk - Allowing Marrow to attack twice in one turn. This effect was shown to last up to two turns, but it could have been interrupted by the use of Chocolate Milk.
 * Banana Milk - This allows the user to use the attack Bone-Bone Explosion.

Known Attacks
Bone-Bone Explosion: A bone Gatling gun attack regarded as his "Ultimate Move". It was shown to do 47 damage and that was on the lower end. (Pure numbers show it as 8d8 making its average 36 damage)

Bone Hand: A swiping attack using any large bone limb currently available.

Bone Gun: A sharpened bone projectile.

Unnamed Bone Arm Attack: Turning the users whole arm into bone, the user strikes through the chest of an opponent usually resulting in death.

Location
The Hone Hone no Mi is likely in the somewhere in the Tarako Kingdom, although the Marines could've taken it after the chaotic events involving Valve, Marrow, and the Crew.

Trivia

 * In reference to One Piece's running gag of milk healing bones instantly, drinking different types of milk change the effect of the Hone-Hone no mi.
