ScottishDuck17 plays Clockwork Knight - Part 7 of 8

Reposting the entire boss strategy plus what happens afterwards, because it's a lot better if I did.

Attic

Level 3

The boss here is almost a clone of the second boss, much like the third boss was a clone of the first. You'll have to hit him in the chest again, but instead of flying around, he jumps around, lowering parts of the platform as he goes. Keep going to the left, hitting him in the chest whenever you can and avoiding both his punch and spin attacks, and when he jumps to the leftmost end, run under him as he's in the air.

From this point, he'll keep jumping around until the entire platform you and he are both standing on is destroyed. Get in as much damage on his chest as you possibly can. When you reach the floor below, the boss will fall apart and lose his head, but the rest of him will revolve around that chest cavity that he has for a weak point. Throw his head at him as the parts start to float towards the chest cavity for a few free hits, then grab the head and stay away from the guy. When his parts are all in a perfect halo, wait for that halo of robot parts to go vertical before throwing his head at his former chest cavity, as you want to throw the head at it when it's exposed. 

After this, he'll try to follow you around and try to crush you with the remainders of his tattered body. Keep dashing, so the attacks will clearly miss you, and throw the head at the cavity when it's unprotected. It will then start going up and down as it moves back and forth (hey, free hits), then the parts will move to both sides on the chest cavity and start rotating in a counter-clockwise direction (stay directly underneath the chest cavity and don't let the "arms" hit you, and run to the side when you get an opening and throw the head at the chest cavity).

For his last attack phase, his severed limbs will be gone and it's just you and the chest cavity. The chest cavity will home into you and try to damage you, and the wireframe shows where it's going to go. If you can trick it into going into the air and also go long distances, you'll give yourself some better chances at throwing the head at it, doing the last bits of damage against this thing and killing it off. You'll also be able to rescue Princess Chelsea, who was stuck in that chest cavity. 

Final Boss

If you're on training mode, you won't get this boss. If you're on Normal or Hard, congratulations. Welcome aboard!

The boss here is a television set with a bunch of claws. Attack the claw that comes down at you, and you'll finally make the boss angry. He'll try to kill you with his face (don't ask), and a can of pencils will come down. Push (or pull) the can of pencils around so that the TV attacks it, and you'll do more damage to it. He'll then attack you with two claws that come down. Attack one of them. He'll do the face strike thing again, and after another hit from a can of pencils, the two claws will rotate in a tight circle. Hit one of them quickly!
