Play As Yoshi In Sonic The Hedgehog 2
Tails has long been Sonic's animal companion, but what if Mario's dino pal jump over to the other side and joined Sonic on one of his adventures? Speculate no longer; it's possible thanks to a new mod.
Modder Shiryu put together this slick hack for Sonic The Hedgehog 2, which not only adds Yoshi to the game, but also emulates a lot of the mechanics from Yoshi's Island. It certainly looks more fun than Sonic '06.
