Star Yoshi

Star Yoshi is a form of Yoshi that only appear 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 (7 in NES version; 6 on the Game Boy version), 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.
