Okay, this is probably ruddy obvious, but in case there are folks who really don't know how the level works: it comes down to a lot of luck. Basically, working from the top down if you can (as with all MB levels) try to clear the shields to get to the switch that will start the conveyor belt. Once you've done this, the button on the belt will move up. If you can get the button accessible (up 3 or 4 rows), try to get back to the switch to STOP the conveyor and then work on trying to hit the button to open the gates that will drop the gingerbread. Try not to hit the switch starting the conveyor belt again (which might make the button inaccessible again), since you'll need a lot of moves (unless you are very, very lucky) to get the button. I've played this level ten times, but got two stars after the first seven times. Still haven't gotten the third star though (although there are levels I've played over 30 times just to get that 3rd star). Good luck. And it gets harder.
