I have adored Yoshi for the majority of his nearly 30 year history, however, I hated him in this game.
He's in the speedy class of characters, which I truly feel is the weakest of the whole game.
But I can't exactly tell why I'm terrible at Yoshi versus similar characters.
I'd always get frustrated while playing as Yoshi. I don't think I've won even once with our favorite green Mario dinosaur.
