Yoshi Cookie

Yoshi Cookies are the favorite snack of the Yoshis. They are featured as a special item in various Mario titles and also come in a variety of shapes, including flowers, hearts, squares, circles, and even Yoshi's face. Some cookies are chocolate, vanilla, or sugar cookies with icing in their centers, while others carry a checkerboard design.

Yoshi's Cookie
In their debut title Yoshi's Cookie, a puzzle game, Yoshi Cookies enter from either the top or side of the screen as Mario, dressed as a baker, pulls a lever. The plot of the game, in a fashion similar to Tetris or Dr. Mario, is to clear them out as Mario continues to fill the screen with more cookies. This done by pressing the A button and shifting an entire row of cookies. Once a row is, either horizontally or vertically, filled with the same kind of cookie, it is cleared from the screen. The Yoshi-shaped cookie acted like any kind of cookie.

During the Super Mario Land 2: 6 Golden Coins arc, which happens after the Super Mario World arc, Yoshi sends Mario some of his island food as thanks for helping him free Dinosaur Land from Bowser. One of the presents is a living Yoshi's head-shaped Yoshi Cookie named Coshie, who helps him by biting and eating everything it faces.

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Mario and Yoshi are required to bring Yoshi Cookies to Boshi in exchange for a race. Yoshi Cookies can also be used in battle to summon Yoshi, where he will attempt to eat an enemy. If successful, the enemy is transformed into an item (a specific item for each type of enemy) that is given to the player. If unsuccessful, Yoshi gives the player a Yoshi Candy. Bosses and some enemies can never be eaten by Yoshi.

There is a magenta Yoshi near the GOAL letters that can store Cookies for Mario, up to a limit of 200. If the number of cookies goes over the 200 maximum, the Yoshi will eat the rest.

Game & Watch Gallery 4
In Game & Watch Gallery 4, the Modern version of Mario's Cement Factory replaces cement-making with cookie-making. The cookies are from Yoshi's Cookie.
