Store water. Laplace is a character in Poké mon, which has two characteristics, water storage and hard shell armor. The water storage characteristic is that it will not be hurt when it is attacked by water attributes, and it will restore blood volume. The characteristic of hard shell armor is that it won't hit the key when it meets water. The water storage characteristics are good, because the blood volume will recover and will not be killed, while the hard shell armor characteristics will not be killed, but the blood volume will gradually decrease and eventually die. Therefore, the water storage characteristics are good.
