In “The Legend of Zelda: Echoes of Wisdom,” the Hidden Ruins is a secret cave located in the southern part of the Faron Region. To access it, players should warp to Blossu’s House in the southeast corner of the region and then head west. Upon encountering torches, proceed north up the stairs to a pond with two unlit torches and a Drippitune enemy. Defeating the Drippitune stops the rain, allowing the torches to be lit, which reveals a hidden staircase leading to the Hidden Ruins.

Within the Hidden Ruins, players undertake the “Cotton-Candy Hunt” side quest, which involves solving electricity-based puzzles and culminates in a boss fight against Smog. Successfully completing this quest rewards players with the Curious Charm accessory.
