Orochimaru's Hideouts

Kabuto's Laboratory is built into the side of an island located in a large body of water. It is first seen when Orochimaru brings Kabuto to the building to explain the reason he was attacked by Nonō and how it was part of a plan engineered by Danzō. Orochimaru than explains to Kabuto that the building they are in is a Medical Laboratory created for him to use.

The lab is covered in medical equipment, ranging from Scalpel to test-tubes. The lab's most unique feature however is the large blood extracting machine in the center of the room. One of the room's massive walls is covered in ceiling length shelves stacked full of jared animals, books, scrolls, crates, and tools. Kabuto later comes here to transfuse blood of Orochimaru's true form into himself.

Trivia

 * In the background, several tanks contain large Snakes. Strangely, one of the snake's upper body is Human, giving it the appearance of Orochimaru's Slithering Snake Mode, possibly one of the experiments that led to the development of the technique.
 * Several years later the same tanks are strangely empty. Possibly due to completion of the experiment.
