If you search carefully, you will see an old man not far away. The old man would speak to you telling you that he requires a Hibiscus Position to wake them up.
Your next stop is the graveyard of the village where you can find the hidden dungeon by pushing the largest gravestone. You will have to fight Shadow Link. You will receive a Hibiscus position after defeating him.
