Giant Crustacean

This giant crustacean is a summon of Pain.

Appearance
Though resembling a normal crustacean, this summon has a number of chakra receivers one being stuck through the top left side of its back and another in the lower right side of its back also, implying it is being controlled by Pain. Around its mouth and all of its underside are coloured white while the rest is a reddish colour. It has eight crab-like legs and two big crab-like pincers. It has many large spikes jutting out of its lower back area, most notable the very large spike in the centre of its lower back. It appeared very dark inside of its mouth.

Abilities
This crustacean is able to use Water Release techniques such as the Water Release: Wild Bubble Wave technique. It is also very durable seeing as it is armoured.

Tale of Jiraiya the Gallant
It is summoned during Pain's fight with Jiraiya, where it uses the Water Release: Wild Bubble Wave technique to wash Jiraiya's oil off Konan. It was later defeated by Jiraiya's Wild Lion's Mane Technique.

Invasion of Pain Arc
In the anime, the crustacean is summoned once again during Pain's invasion of Konoha to rampage in the village.
