Super Mario Flash 2 is a 64-level extravaganza that sends Mario up against Bowser, king of the koopas. As Mario, you'll stomp on the insidious turtle creatures, crush mushroom-like goombas beneath your feet, and absolutely crush bullet bills, buzzy beetles, and the like. You'll pick up fireflowers and gain the ability to shoot fireballs, which you'll use to burn up the Hammer brothers, spinys, piranha plants, and more.

To locate the secret exit in World 7-4, you will need a mini-Mushroom (in storage, if possible). Make your way past the mid-level point and upwards to the left side of the screen (high up). You will eventually come to a flying "?" block. Use the mini-Mushroom to make Mario smaller and jump onto the block to stop it.
