Any gamer who's been around the block a few times knows it's time to panic when a level's song speeds up. But what if the music sped up exponentially? Turns out you can do just that in Super Mario World. All you have to do is eat green fruit with Yoshi -- which adds 20 seconds to the game's clock -- after every time it dips under 100 seconds [via Nintendo Everything]:
Dude, that's fucking cool. It's so awesome to find old secrets in classic games. I enacted a codec message conversation I've never seen before last time I played MGS... and it was 10 years after its release!!! After the fight with liquid in the Hind-D, when you eventually get down to the snow fields, press you're back up to the right wall in the south-eastern corner (a feat I accidentally did after the Sniper Wolf fight)... and there you have it.
