Into the Heart of the Negativitron

This is the final battle against the Negativitron. You'll have hold of the hamster for this battle. Charge up and land on either of the two weak points on each side of the Negativitron. Be sure to time your falls back to the ground carefully. The Negativitron will respond to your attacks by releasing a huge beam that can instantly nail you. Charge quickly to stay in the air and repeat the pattern. Afterwards, head down either path to face form two.

For this fight, there will be a jump platform on the bottom and various grapple points floating above. Wait for the Negativitron to stop sucking wind and left the platforms come to a halt. Grapple up to the top of the platforms and leap onto the Negativitron's head.

For the last form of the Negativitron, stand on either end of the wall and jump when his lasers land. You can touch his attacks while they are in the air, but will take damage if they hit you on the ground. Keep avoiding the lasers and wait for Da Vinci to hand you a cake. When the Negativitron pounds the ground, throw the cake at his weak point to finish the boss off.
