Also known as the Fire Chomp, these guys are one of very few video game enemies that I’m legitimately afraid of. They’re floating black balls with SHARP TEETH, and they BREATHE FIRE! Not only that, they have an entire TAIL of fire flowing behind them!
AND! When they run out of fire, they EXPLODE! So these guys are serious business.
Don’t fuck with things on fire with sharp teeth. Not just in the world of Super Mario Bros., that’s just generally good advice; If something has sharp teeth and is on fire, it’s probably best to stay away from it. It might explode at you.
