Scarecrow

Scarecrows are sometimes seen in The Legend of Zelda games, serving various purposes.

Ocarina of Time
The first instance of a scarecrow in a Zelda game is the scarecrow named Bonooru seen in Ocarina of Time. Bonooru loves music, and will learn whatever song you play for him on your Ocarina. Another scarecrow also lives near Boonoru, and he enjoys this music as well.

Majora's Mask
Pierre is much the same as his Ocarina of Time counterpart. He loves music and will learn a song played for him on the Ocarina of Time. However, this song must be re-taught to him if the Song of Time is played. If you talk to him, he will offer you to dance. If you accept, time will pass until the next dawn or night. After dancing, he will ask you if you want to learn a way to speed up or slow down time. He will say playing a "mysterious song" (Song of Time) backwards, it will slow down time, and that if you play each note twice in a row, time will move forward.

Twilight Princess
In Twilight Princess, there is a scarecrow near Link's House, with which he practices attacking with his Wooden Sword in the beginning of the game. A few other scarecrows can be seen later as well.

Link's Crossbow Training
In Link's Crossbow Training a bunch of scarecrows are used as targets that Link must shoot with his crossbow.
