Secret Grotto

A secret grotto or simply grotto is a secret cavern or cave found in the world of Hyrule that is sealed either by earth or an enchantment that can sometimes respond to the power of music. The land of Hyrule has a widely unexplored substructure left over from long ago that is made up of cavernous passages as well as smaller caves. It is believed that many of these caves still exist somewhere in the wide world and that they are filled with secrets and treasure just waiting to be discovered. THe Stone of Agony will vibrate when a secret grotto is near.
