If you really want it out, you'll have to go into the defrost ducts inside the dash…

If it's metal, try a narrow pen-style magnet (they look like the old telescopic car antennae) and you can try and attract it. If it's plastic or non-metallic (like CHOCOLATE!), there are tools that you push the end and little grabbers come out (Cheap at the auto parts stores) and maybe you can snatch it out.
Other than that, it's a MAJOR project to remove the dash and heater parts to get to the actual vent system.
If it's hard to see where it went, try a little open-road swerving to line it up to an accessible place. : )

Good luck. In the future remember, "NO M&M's on the dashboard!"
