Yoshi, also known as Dino, Yosh-Yosh or Mario's Little Partner is a DINOSAUR! who is ostensibly Mario's best friend. However, he secretly hates Mario, as he now has back problems from that douche riding on his back. He likes Luigi though, because in all honesty, who doesn't?
He is a playable character in the 1995 arcade fighting game Mario Fighters. He can eat people in the game.
