Another boss stage, Duck Vehicle is a lot different than most of the fights you've experience so far. The Penguin operates the Duck Vehicle, but the goal of this fight is to simply destroy it, not him.
The Duck Vehicle can shoot a laser out of its eye, which you can see charging up when it blinks, and The Penguin will make it charge across the room and then back to where it started. In addition, The Penguin will sometimes throw out two bombs at your location, which you have to move horizontally to dodge.
Your target is the Duck Vehicle's scaffolding, which can only be hit by being in the upper portion of the area. However, since the vehicle will charge, you must be at the bottom of the area to avoid it. The pattern then is to move left and right, dodging projectiles, and then jump kicking the base of the Duck Vehicle when it comes to a halt on the right side of the screen (the left side requires perfect timing, because you have less than a second of a window to strike it).
