Star Yoshi

Star Yoshi is a form of Yoshis that only appears in the game Yoshi. In the game, putting lower and upper halves of a Yoshi Egg together makes a Yoshi slip out of the egg. If the maximum number of characters are between the two halves (which is 7 on NES and 6 on Game Boy), the emerging Yoshi would become Star Yoshi and will award the player with 500 points. The Star Yoshi looks similar to a regular Yoshi, except that there is a Star floating above him, is bulky in size, and the sound it makes is much more lower-pitched than a regular Yoshi.
