A large crustacean, (in the anime, this summon has a number of body piercings, implying it is being controlled by Pain). It is summoned during Pain's fight with Jiraiya, where it uses Water Release: Violent Bubble Wave as an attack and to clean Jiraiya's oil from Konan and was later destroyed by Jiraya who used Wild Lion's Mane Technique. In the anime, a new crustacean is summoned during Pain's invasion of Konoha.

Trivia

 * In the manga, this summon is unique in that it is the only creature summoned by Pain which does not have Chakra Receiver piercings, Rinnegan eyes and tattered wings, suggesting that it was a normal summoned creature acting under it's own will.
