Black Yoshis are a Yoshi variant that first appear in Yoshi's Story. They can first be found in secret areas of World 2. Along with White Yoshis, they has certain abilities that give him advantages over the other Yoshis.
They can be found in large, hidden eggs on pages 2-1 or 2-4. Black Yoshis and White Yoshis are the only Yoshis in Yoshi's Story that enjoy all the fruit, even the red Peppers. In addition, Black Yoshis can eat other things that the rest can't, such as Black Shy Guys. Another special power he possess in Yoshi's Story is that his eggs explode in gigantic explosions, destroying more than one enemy at a time. Black Yoshi has the lowest voice of any Yoshi in the game. If the player loses Black Yoshi, the White Shy Guy cannot retrieve him.
