26The Yoshi Paradox
Super Mario World 2: Yoshi's Island is all about Yoshi interacting with Mario as a baby... but how could that be?
One of the big innovations introduced in Super Mario World—besides those fancy-pants 16-bit graphics and that hard-to-master cape—was the introduction of a dinosaur sidekick that Mario could ride on named Yoshi. The game sets things up to imply that Mario and Yoshi are meeting for the first time—something that is immediately
undone by that game's sequel.
Why does Yoshi seem to show zero knowledge of his previous adventures with Mario? And sure, Mario isn't going to remember being a baby, but how did he then go all those years before so much as crossing paths with a Yoshi again?
