Kanhebi

Kanhebi is Anko's favorite summon, a giant anaconda. She is blue with small dark blue blotches and stripes running along her body. She has many of the same abilities of Orochimaru's Giant Snake that he summoned in the Forest of Death, but she is quite a bit larger, and is able to act as a form of transportation. She can also act as a shield, having high stamina and thick skin, as evidenced by her surviving a cave-in.
