QuackerJack
Hopefully you have the Heavy Gas ready with at least 16 ammo (8 shots) otherwise this battle is a little difficult.
 * Health: 16
 * Reward: 5,000 points

When you enter the room, you'll notice Quacker Jack at the bottom of the screen and a little guy at the top (an alive version of Mr. Banana Brain). The two will begin to move, signaling the start of the fight.

The two guys act completely different. Mr. Banana Brain will try and match your horizontal location and then drop banana peels in an attempt to hit you. Quacker Jack, however, just runs around trying to avoid you (he will run into you though if you let him). If you do nothing, Quacker Jack will run back and forth indefinitely. When attempting to fight him, Quacker Jack will try and jump to another level if you get down on his. If you shoot him, he'll stop in place and then jump to another level.

Heavy Gas Strategy
Simply avoid the bananas, drop down on the lowest platform and hang. Drop a Heavy Gas on the ground, jump up, dodge Mr. Banana Brain and repeat. It only takes 8 shots with Heavy Gas to kill Quacker Jack.

Normal Weapon Strategy
There's no real procedure for doing this, since there is some randomization and such, but just keep the following in mind as you attempt to defeat Quacker Jack:
 * Always stay as far away from Mr. Banana Brain as possible.
 * When going up a level you can chase Quacker Jack so that you hit him immediately after he lands.
 * When going down a level to attack Quacker Jack, make sure he is a safe distance away so that you give yourself time to drop down twice.
 * Go at your own pace: Quacker Jack will never change levels unless you cause him to so focus on avoiding Mr. Banana Brain's attacks and running into Quacker Jack.

Steelbeak
Steelbeak is both the hardest boss in the game and the only one with two parts (essentially twice the health).

Part One
When you enter the room, Steelbeak will be sitting in a control room in the upper right. Two small flying mechanical units will attempt to destroy you by running into you and firing small purple projectiles at you. Your goal is to destroy the window noted by the two glowing markers on the left side; it can be destroyed by shooting between them. There are two ways to do this: you can either use Thunder Gas and fire from the ground near the bottom left corner of the room, or you can (and probably will have to) climb up the candelabras and fire normally at it.

There is just one simple way to get through this without dying: first kill the two robots that start in the room. Try to kill them one right after the other. Immediately climb the objects on the wall and hang onto the one on the upper left. Face Steelbeak, and just keep firing. Whenever a robot respawns, destroy it while it is flying downwards on its starting path (during this small amount of time, they won't try and attack you). This way, you'll be able to kill off the minions while you go after Steelbeak.

Eventually the glass will shatter, a full health box will appear, and Steelbeak will take an elevator down to the floor to face you himself. Remember to heal if need be.

Part Two
Steelbeak will begin by running back and forth like a crazed chicken. If you drop to the floor to get a shot off at him, be ready to jump! After getting hit he'll pull out a large metal block and throw it at you before pulling another one out and using it as a shield. While he's using it as a shield, climb to the top left or right wall object and wait for him to reach the opposite side of the room. Drop down while he's running towards the wall (not after he's reached it), pop off a shot, then jump back on the wall. If done right, he'll throw the metal object away and begin running around again without any defense. Simply repeat this process to win!
