The Dark World of Deltarune Chapter 3 plunges Kris, Susie, and Ralsei into the chaotic game show "It's TV Time!" hosted by Tenna, a living television. Throughout the show, Tenna frequently calls out to his unseen co-worker, Mike, revealing his reliance on him. Upon returning to Castle Town later in the game, you'll discover a building marked "TV" containing a long hallway that leads to a mysterious door labeled "Mike."This guide will walk you through how to find and open Mike's door, navigate his inner room, and ultimately defeat him in battle.

Deltarune: How To Get Into Mike's Room

Mike's door is located at the end of a long hallway within the TV building, which is situated above the Cafe in Castle Town. You can first encounter this door at the beginning of Chapter 4. Initially, you'll find it locked and requiring a code.
  • Door Taped Up? If the door is taped up, it indicates that you failed to recruit enough employees from Tenna’s show in Chapter 3. To recruit employees, you must engage them in battle and choose to spare or pacify them instead of defeating them. Many can also be recruited simply by progressing through the story.
  • Getting the Code: To obtain the door code, you must first finish Chapter 4.
  • After beating the final boss and watching the credits, load up the save file you used to complete the chapter.
  • Upon loading, you'll be sent back to an area just before the final boss fight. Here, look for a red teardrop object next to some steps below the save point.
  • Interact with the red teardrop to be returned to the previous save point.
  • At that save point, you'll see a pink teardrop. Interact with it and choose the option to "take you to the beginning."
  • You will then find yourself in front of a large door. Next to it is a green teardrop. Walk past this teardrop to the right and continue walking until you see a spotlight. Interacting with the spotlight will transport you back to Castle Town.
  • Important Note: When you return to Castle Town via this method, Ralsei and Susie will not be accompanying you. Be prepared to face challenges alone.
  • Retrieving the Code and Opening the Door:
  • Upon returning to Castle Town, you'll notice that all other areas and buildings besides the TV building are blocked off.
  • Head north past the Cafe and enter the TV building.
  • Proceed down the hallway to Mike's door. Next to the door, you should now find a note.
  • Read the note to reveal the code: "6453".
  • Enter this code into the door to remove its lock.

How To Enter Mike’s Inner Room

Once you pass through the first Mike's door, you'll enter another long hallway.

  • First Cat Statue: Walk to the very end of this second hallway, where you'll find a short cat statue. Pet the cat statue to reveal yet another hallway.
  • Blocked Room & Tall Cat Statues: In this newly revealed hallway, there's a room to the north that iscurrently blocked by several tall cat statues. These are too high to pet manually. You'll need a tool to reach their heads.
  • Find the Mouse Arm:

  • Go to the next hallway on the right. You'll see a tall cat statue by the entrance and several hats hanging from the wall.
  • Head all the way to the very end to find a mouse that is frightened by a nearby cat statue.
  • Pet the cat statue to make it disappear. The grateful mouse will then transform into a stretchable arm that you can control with your mouse cursor to reach short distances.This arm can also be used to grab the different hats in the room andplace them on Kris’ head.
  • Treasure Chest: Before returning to the hallway to the west, pet the tall cat statue in this hallway (the one with the hats) to reveal a treasure chest.
  • Clear the Path: Head back to the hallway on the left (where the blocked room is). Use your new mouse arm to pet the tall cat statues blocking the northern room, getting them out of the way.
  • The Microphone Room:Enter the room above you. Inside, you will find a save point, a largemicrophone, and another door to your north also named "Mike."
  • Adjust Mic Settings:

  • Use the large mic on the left to adjust your microphone settings.
  • Set the audio input to a working microphone connected to your computer.
  • Adjust the sensitivity of your mic. The goal is to set the sensitivity so that your normalspeaking volume reaches the tip of the green bar on the meter. If it'stoo sensitive, your input will frequently max out. If it's too low,you'll need to shout. Precision here is key for the upcoming challenge.
  • Open the Final Door:

  • Once satisfied with your mic settings, you can proceed to open the northern door.
  • You need to fill the door with color using your voice. The door requires your maximum volume to fully unlock.
  • When you've completely lit up the door with your voice, you'll be able to enter. Save your game beforehand, as a fight awaits you inside.
  • How To Beat Mike

    As hinted by the previous room, the fight against Mike heavily utilizesyour microphone. You'll need precise control over your voice's volume to dodge attacks and use your new mouse hand to interact with enemies.

    The First Phase Of Mike's Fight

    In this phase, the loudness of your voice determines how high you jump. Maintaining a certain volume will keep you at the corresponding height, while becoming silent will make you drop to the bottom.

    • First Attack:
      • Signboards will appear at the top of the screen.
      • When the sign says "Applause," make your voice as loud as possible to jump high and dodge the microphones that appear below.
      • When the sign says "Shut Up," make no sound (remain silent) to drop to the bottom and dodge the microphones that appear above.
    • Second Attack:
      • Microphones will approach you from the right side of the screen.
      • These mics extend in height, requiring precise volume control to adjust your jump height and avoid them.

    The Second Phase Of Mike's Fight

    Mike takes a break, and a cat-like stand-in (also a "Mike") replaces him.Your volume still controls jump height, but you'll also use the mousehand to pet various cats.

    • First Attack:
      • Several small cats will approach you from various directions.
      • Pet them with your mouse hand to make them disappear and avoid damage.
    • Second Attack:
      • Large sleeping cats will be in the four corners of the battle area.
      • As time passes, these cats will turn an increasingly dark shade of red, indicating their agitation.
      • Pet them to appease them and prevent their attacks.
    • Third Attack:
      • This is a combination attack, featuring Mike's second attack from the first phase (mics coming from the right) alongside pillars of cats also approaching from the right.
      • You'll need to dodge the mics with your voice while simultaneously petting the cat pillars to clear them.

    The Third Phase Of Mike's Fight

    You will now face "Big Mouth Mike." In this phase, your voice controls movement along a horizontal line instead of vertical jumps.

    • First Attack:
      • A red light will flicker, indicating where a large paw will strike from either above or below.
      • Use your voice's volume (or lack thereof) to position yourself horizontally in a safe spot to avoid the paw.
    • Second Attack:
      • Small paws will rain down from above.
      • Use your voice to move horizontally and avoid these falling paws.
    • Third Attack:
      • A harder version of the first attack, where up to two paws will strike simultaneously, requiring more precise horizontal positioning.

    The Fourth Phase Of Mike's Fight

    The final phase combines all three Mikes and their respective attack mechanics.

    • First Attack:
      • You will move along the horizontal line.
      • Pet approaching cats (similar to Phase 2) and place blue cats on a bed (new mechanic, likely involves interacting with beds as they appear).
    • Second Attack:
      • Avoid the large paws (from Phase 3) while simultaneously petting the large cats on the opposite ends of the horizontal line (similar to appeasing cats in Phase 2).
    • Third Attack:
      • Avoid the three individual Mikes (likely as projectiles or obstacles) while petting them to deal damage.
      • Additionally, continue to pet the large cats to keep them from attacking you.

    Successfully beating Mikewill transform Mike's room into an area filled with various minigames,allowing you to re-experience and practice the unique voice- andmouse-controlled mechanics introduced during the boss fight.
