Ocarina of Time Scarecrow's Song
In Ocarina of Time, Link can learn the optional Ocarina Song, the Scarecrow's Song, allowing him to uncover secrets and shortcuts found throughout the world. Below is a full guide on how to learn, activate, and use the Scarecrow's Song, allowing with all 13 locations where the scarecrow can be summoned.
Creating the Song
As a child, make your way over to Lake Hylia and head to the small fences at the northeast part of the area where you will find two Scarecrow's here. Speak with Bonooru, who is located at the bottom and he'll tell you that he never forgets a tune. Put him to the test and pull out your Ocarina. Make up your own Ocarina Song and memorize the notes. It must be at least 8-notes, so I suggest an easy to remember pattern.
Activating the Song
As an adult, return to Lake Hylia and head back to Bonooru. Pull out the Ocarina and play the same 8-note song that you played to Bonooru as a child. This will activate the song, allowing you to play it in specific locations throughout the world. If at anytime you forget the Scarecrow's Song, you can return to being a child and repeat the whole process.
How It's Used
Throughout the Overworld and within specific dungeons, there are specific spots where Navi flies over to an area and turns green. All 13 of these locations, which are listed below, allow you to play the Scarecrow's Song to summon Pierre. Link can then use the Hookshot or Longshot to reach Pierre and find whatever secret or shortcut lies ahead.
Location: After reaching the checkerboard floor room in the Forest Temple with the falling ceiling, Link can head out a nearby door to reach the Northeast courtyard.
Purpose: This serves as a shortcut, making it much easier to reach the later portion of the dungeon, without having to backtrack.
Location: Inside of Dodongo's Cavern. From the main chamber, head through the door to the southeast and you can summon Pierre on the higher ledge.
Purpose: Grappling up to Pierre allows Link to reach a Scarecrow that he previously could not reach.
Location: Located in half-circle room of the Fire Temple. This is the room where there are multiple large boulders that are rolling around. When Link first enters this room on the second floor, he can turn to the right and look up to find a platform. He can play the Scarecrow's Song to summon Pierre.
Purpose: This allows Link to reach one of the optional large rooms at the top of the Fire Temple, where he will find two Gold Skulltulas along the way, as well as a Huge Rupee.
Location: In the Shadow Temple, after taking the boat ride and then crossing the void, just before the boss, you can play the Song of Time to reach a higher ledge and get some recovery hearts. From here, you can then play the Scarecrow's Song to get Pierre to appear on a higher ledge.
Purpose: There are a few more Recovery Hearts here, just before the boss battle with Bongo Bongo.
