Super Beast Imitating Drawing

By infusing his chakra into the ink beforehand, Sai can draw objects with a brush on his scroll (something he can do very quickly) to animate the ink directly off of the page. These creations grow to life-size once they have been brought to life--similar to Deidara's Exploding Clay constructs. Sai typically creates giant birds for long range transport, lion-like monsters for attack, or objects like umbrellas for everyday use. For discreet communiques when he is undercover, Sai is able to turn the words he writes into small animals, allowing them to travel to their intended target unnoticed.

Since they are made of ink, a single blow is usually enough to dispel them. The one exception to this are snakes, which are used as living ropes to apprehend a target; they have been shown to be abnormally difficult to tear.
