Blindfold Boo

Blindfold Boos are a rare type of Boo found in Yoshi's Story. As their name suggests, these Boos are blindfolded and appear with a pair of big pink ears on each side of their heads. As they cannot see where Yoshi is located, they trust in their auditive senses to perceive the Yoshi's location and then attack. As such, Yoshis have to move quietly past them.

Trivia

 * Blindfold Boos bear a notable resemblance to the blindfolded Boo Man Bluffs of Super Mario World 2: Yoshi's Island.
