Shieragucchi are enemies in the Game Boy Advance game Wario Land 4. They are found underwater in the level Mystic Lake. In S-Hard mode, they also appear in underwater areas of Wildflower Fields, Domino Row and Crescent Moon Village. They are big clams with angry eyes and green spikes.

Shieragucchi stay in one place and about half of their body is hidden in the ground. They do not leave their place until Wario swims neaby. When he does so, Shieragucchi quickly move up for a rather short distance and open their shell to reveal their sharp teeth. Afterwards, the clams return to the ground again. They never move horizontally. When touching their sharp teeth or their spikes on the side and above, Wario will take damage, and they also pull him down when Wario gets between the two halves of their shells. A Shieragucchi is immediately defeated and leaves a Small Coin when Wario touches the unprotected part of its shell from below.
