Blindfold Boo

Blindfold Boos are rare Boos in Yoshi's Story. As their name suggest, these Boos are blindfolded and appear with a pair of big pinky ears on each side of their heads. As they cannot see where's Yoshi, they trust in their auditive sense to perceive him and attack then. In that case, Yoshis have to move quietly past them.
