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 and some are vanilla. And some are sugar cookies with icing in their centers or 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.
