Over the years, folks have found a ton of glitches inside of Super Mario Bros. 3—so even if you've played it before, chances are good that there's still stuff you've never seen inside the game.

Some glitches are small, but neat. Some glitches are huge and ridiculous, like the one featured in the initial GIF in this post—where Bowser loses the ability to breathe fire at you. A+Start walks us through lots of them—not only showcasing what they are, but the specific conditions necessary to replicate them yourself. The video includes:

A crouch block glitch, which lets you circumvent blocks (plus, places you can use the glitch to great effect—like to get to special rooms or bosses, for example) What glitches appear if you go into specific stage backgrounds A map glitch which lets you venture into a void An airwalk glitch A stage where a bush can turn into a block A mushroom glitch which causes another Mario sprite to appear Getting a mushroom to kill a paragoomba How to get a green shoe to glitch onto your Tanooki suit Places where turning into a statue will accidentally kill you How to come across an unused sprite How to warp instantly into a boss room Endless Mario somersaults How to get weird vine spawning An item disappearing glitch Where the game spawns strange invisible enemies How to get a Boom Boom to swoop completely out of the level How to get Bowser to stop breathing fire in the final boss battle—making the battle way easier How to get stuck inside a pipe How to get to the final screen by glitching through an earlier stage The many places you can glitch to and get stuck in

And more! Mind, many of these glitches are level-specific, but A+Start is clear about where and when you can do some of this stuff.
