Level 25:  Jump up to the middle of the room before he starts moving and get the
           power to breath fire. The easiest way to defeat him is to stand on
           the highest platform and shoot him on his highest jumps. You will
           only have to dodge when he tries to jump underneath you.

Level 50:  Like before, gather the powerup before he starts moving. Learn the
           pattern of his movement and attacks before trying to shoot him.

Level 75:  Again, get the power up quickly. Stay on the level that hangs about
           where his head is when he jumps. Shoot at him when his head is your
           level. Watch out for the fireballs he throws, but once you learn his
           pattern they get easier to dodge.

Level 100: The final boss. The powerup in this stage works a little differently.
           You gain the ability to shoot lightning bubbles which need to be
           popped in order to be effective. I recommend climbing up the
           platforms while the boss has his back turned to you. Then jump toward
           the wall and press the attack button as fast as you can. As you move
           down the wall, you will fire a steady stream of lightning bolts at
           the boss. These bolts will also destroy the projectiles he throws at
           you. Don't stand in the corners too long or you could get nailed.
           Like the bosses before, once you learn his patterns he shouldn't be a
           problem.
           Note: After defeating the final boss, you will receive a password
                 which will start you over at level 1 with harder enemies. The
                 bosses will need more hits to defeat, but their patterns remain
                 the same.
