The follow page describes each of the bosses that Milon will encounter when trying to retrieve the seven crystals. The number of hit points indicates exactly how many bubbles Milon must strike the head of the boss with the defeat them. This number is cut in half if Milon purchases the Excalibur tile. Body Damage and Projectile Damage reflect exactly how many bars Milon will lose when hit by the body of the boss and the projectiles he throws respectively.
To defeat the bosses, Milon must strike their heads with bubbles. At the start of the game, this can be considerably difficult. With small bubbles and a limited range, you'll have to position Milon as close to the boss as possible and fire frequently to take them down. The story changes considerably when you have the third crystal, and purchase the Super Shoes and Blimp. When you have these items, you can stand just ahead of the left door, and jump up into the air. Fire downward at the boss' head as it is approaching, while holding the jump button to sustain your height in the air as long as possible. From that range, you should be able to hit the boss a number of times while avoiding the majority of the projectiles. Be careful, though, with the last boss: Kama. This is because he throws projectiles much more rapidly and aggressively than any of the others; dodging them is a lot more difficult since more than one projectile may be on screen at once, potentially cornering Milon.
