Yoshi is Mario's friend and he is a green dinosaur who likes to eat things. Yoshi licks bad guys in Super Mario 64 DS and many of the other Mario games. Yoshi's first game apperance was Super Mario World. Yoshi is on games including his popular Yoshi's Island which Yoshi takes Baby Mario on traveling adventures, and Yoshi Touch and Go! Mario rides on Yoshi's Back in the Super Mario World game! He is pretty good character in my opinion.
