"The unusual liquid substance that covers that area is known as Waking Water, and it has certain unique properties. If you make contact with Waking Water, the Guardians will be immediately alerted to your presence."

Waking Water is a special type of water that can be found in the Silent Realms. It is located mostly on the same locations as the water in the real world. In some locations, pools will ebb and flow from the ground. Interestingly, Waking Water is solid when walked on.

When Link touches the Waking Water, he will not sustain any damage, but the Guardians will immediately be awakened.
