A Blindfold Boo

Blindold Boos are boos that cannot see, but can hear Yoshis by the Yoshis making noise. They are invincible and only appear in one level of Yoshi's Story. There is a Boo called Boo Man Bluff that appears in Super Mario World 2: Yoshi's Island that acts the same as Blindfold Boos. Blindfold Boos also appear in Super Princess Peach, but their design is slightly different from the Yoshi's Story version.
