Waking Water

Waking Water is a slightly silverish liquid in Skyward Sword and is found only in Silent Realms. If Link touches the water, the Guardians will awaken and give chase to Link, negating the effects of an active Sacred Tear until the next one is collected. Sometimes, the water will rise in a spot, then recede and disappear, then rise again.

Trivia

 * If Link looks at the Waking Water, he can see the Triforce with the Goddess symbols in the center of each triangle. For some reason, Farore's and Nayru's mark appears on the left and right respectively, where it should be the opposite.
