This is the only Baby Yoshi that cannot be found on the World Map, and therefore, cannot be taken into other levels. In addition, its light-based abilities are only functional in dark areas. However, if the players carry one to the goal, the Glowing Baby Yoshi gives an extra life and remains behind in the fortress, unlike the other Baby Yoshis that remain in front of the building and then follow the characters when they enter. The Glowing Baby Yoshi is only found in the levels Fire Snake Cavern and Which-Way Labyrinth. The only other appearance it makes is in the credits scene, dancing with the other Baby Yoshis and the Red Toad House, where they either hold a Toad icon or a Bowser icon.
