Shieragucchi

Shieragutchi (シエラグッチ) are enemies in Wario Land 4 that are found underwater in the level Mystic Lake. In Super Hard mode, they also appear in underwater ares of Wildflower Fields and Crescent Moon Village. They are big clams with angry eyes and green spikes. Shieragutchi stay in one place and about half of their body is hidden in the ground. They will not leave their place until Wario comes near. When the treasure hunter does so, Shieragutchi will quickly move up for a rather short distance and open their shell to reveal their sharp teeth. Afterwards, the clams will return to the ground again. They never move horizontally. When touching their sharp teeth or their spikes on the side and above, Wario will be hurt, and they will also pull him down when Wario gets between the two halves of their shells. A Shieragutchi will be immediately defeated and leave a Small Coin when Wario touches the unprotected part of its shell from below.
