Take coffee, roundabout and spread shot and super number 1. First phase: Use roundabout. Easiest phase, just shoot the ducks and watch out. Second phase: Switch to spread shot. Try to parry as much as you can. Shoot the ballon head clown, but not so much, because you WANT TO FINISH HIM WHEN THE 2ND TRAIN IS IN ITS HALF (just like in the video). This is very important!!! Third phase: Take spread shot. If you get lucky and his first attack is green horse, you can finish him in one go. If you get unlucky (like I did), and get yellow horse, just get under the horse and shoot up with the spread shot. Fourth phase: Take spread shot. When you see the train is coming in the background, move to the moving platforms. When he spawns the penguins, quickly go to the side of the first 2 penguins and kill them. Then move and kill the other 2 penguins. This way it is very easy and works 100% of the time. Good luck!
