Then, hours later after we started playing, the Yoshi stopped and walked toward the screen at us.
It hadn't spoken at all since we started, but now it suddenly felt inclined to speak directly to me. "Seems like you're having a lot of fun playing with me inside my world," it said, it's tone somewhat sinister, as if the way it gazed directly in my eyes at that moment wasn't unsettling enough. "That's good... because I've been having A LOT of fun playing with you..."

I was afraid to look, my body feeling different from when I started playing. But as I turned to gaze, the game's purpose became all too clear.

"Welcome to Yoshi's World. I'm sure I'll enjoy my stay..."

When Yoshi plays, everybody wins (an egg).
