Giant Clam

Overview
The Giant Clam was the personal summon of the Second Urinkage. Unlike other summons, this clam seems to lack its own personality and is completely loyal to its summoner regardless of the intention, even if it means fighting Uringakure shinobi. Aside from its massive size, it resembled an ordinary clam. Several prominent dark lines encircle both the upper and lower portions of its shell, while the Uringakure symbol is inscribed upon its top.

Abilities
The creature is capable of producing a mist with which its summoner can create a deceptive mirage that completely rendered observers unable to accurately locate the position of itself or its summoner, after firstly opening its shell and exuding a mist from its siphons throughout the duration of the technique. Its shell was very sturdy, being able to resist almost any attack. This creature also seems to have an extraordinarily long life span as it survived until the Fourth Shinobi World War.
