Yoshi is a fictional video game character from the Mario series. He was created by Nintendo to be Mario's loyal friend. He is a green dinosaur who lived on Yoshi's Island and first appeared in Super Mario World.
Yoshi is a member of a dinosaur-like race known as Yoshis. Yoshis contsitute a long, sticky tongue that they use to find and eat food from a distance. The character Yoshi has made extensive use of this tongue with Mario's help to defeat Mario's enemies (Goomba's, Koopa's, ect.). It has also been used as a sort of rope in Super Mario Galaxy 2. Yoshi's most visible feature is his large nose, this helps him and the others find and dig out food underground. Yoshis come in a wide variety of colors. All Yoshis have a shell on their back. All Yoshis hatch from eggs. Although many Yoshis prefer fruit, they will indeed eat other things (like Goombas, for example) as a way to defeat enemies. Despite their short legs, Yoshis can run quite fast, and can even float in the air by quickly kicking their feet in a move known as the "flutter jump". Also, in Super Smash Bros. Brawl, Yoshi's Final Smash allows him to fly and breathe fire.
