Yoshi Cookie

Not to be confused with the game Yoshi's Cookie.

Yoshi Cookies are items that appear in the Mario series. They first appear in the game of the same name Yoshi's Cookie.

Super Mario RPG: Legend of the Seven Stars
Yoshi Cookies first appear in this game where they are the main items of Yo'ster Isle. With a Yoshi Cookie, Mario can feed Yoshi them in order to keep up his speed. This is helpful for trying to beat Boshi in the race. If Mario and Yoshi win the race, they are awarded with more Yoshi Cookies that can be used in battle. When a Yoshi Cookie is used in battle, a Yoshi will appear and eat the cookie. There is a chance that the Yoshi may eat the enemy and it will disappear from the battle (though, no coins or EXP are earned from this). However, the enemy is instead turned into a random item.

Paper Mario
