Upon pushing both of the buttons, the door will open, revealing a set of stairs that leads off onto a giant industrial fan.

Use this fan to float upward to the next platform—be careful to maneuver around the lasers, though!

Once you reach the platform at top of the wind tunnel, you should be facing a small hallway that leads to the library—walk through this hallway and into the library

Inside the library should be an NPC with the words "I think there's a secret this way!" floating above their head. Follow where this NPC is pointing to reach the Secret Boss stage.

To begin the boss fight, press the red button in the middle of the stage.

When the boss fight begins, you'll be given the Laser Cannon 6000—use it to shoot MR STINKY-INATOR and lower his health. Make sure to keep as much distance from him as you can though, his hat throw move will kill you upon impact!

As soon as the boss reaches zero health, you will earn the SECRET BOSS DEFEATED badge. Congratulations!
