Teaser Room
Entering the door directly in front of the player will lead to a puzzle room with a TV screen and four character icons surrounding it (two on the left, two on the right). Chucking Bacon Soup cans at these symbols will cause them to flip around and show the monster forms of each character. From top left to bottom right, these are Shipahoy Dudley. Boris the Wolf, Alice Angel, and Bendy, which are flipped into Shipahoy Wilson, Brute Boris, Alice Angel (ink form), and the Ink Demon respectively. A question block from Boris and the Dark Survival can also be found in this room, as well as a Boris hand protruding out of the floor that can be interacted with.
Triggering the correct symbols will reveal different teaser images for upcoming projects in the Bendy franchise. Currently, there are five known teaser images that have been found.
If the player inputs Shipahoy Wilson, Alice Angel (ink form), Brute Boris, and Ink Demon, it will be revealed that B3NDY is in the works.
If the player inputs Shipahoy Wilson, Alice Angel (ink form), Boris, and Bendy, a teaser for Bendy: The Silent City is revealed.
If the player inputs Shipahoy Dudley, Alice Angel (cartoon form), Brute Boris, and Ink Demon, a teaser image revealing an ink monster chained up to some poles will appear on the screen. This is presumably a teaser for Bendy: The Cage.
If the player inputs Shipahoy Dudley, Alice Angel (cartoon form), Boris, and Ink Demon, a teaser image showcasing a new character named Fluffsy standing in front of their milk bowl, with a milk bottle to its right, appears on the screen.
If the player inputs Shipahoy Dudley, Alice Angel (ink form), Brute Boris, and Ink Demon, a teaser image of Boris holding a pan will appear on the screen. This is presumably a teaser for Bendy: Lone Wolf.
Bendy Mascot Costume
A Bendy Mascot Costume can be seen in the main area. If the player turns their back to it, it will stare in their direction and move closer to them each time they turn around. It can be heard whispering the lyrics to Build Our Machine by DAGames if it's standing right behind them. Chucking a golden Bacon Soup can at it will reset the game and the player will still be holding their golden soup can. If the player enters the Drawing Room again, the player will stumble upon the same mascot costume in the corridor. Chucking the soup can at it again will cause another reset to the game and the whole area will be shaking. Turning around will reveal a giant mascot costume lurking in the darkness. After a few moments, the costume vanishes and the game crashes. Furthermore, the mascot's whispering audio files in the game files are numbered "2219124", "152118", and "131389145" which translates to "BUILD OUR MACHINE".
Bendy
When running over to the Oldtime Theater after opening the gate and looking back to the Vending Machine, Bendy will appear in the small vent next to it for a few seconds, before ducking out of view.
Similarly, if the player goes up to the door to access Riley's Memories without breaking the windows, a small vent near the Teaser Room entrance will have Bendy pop up again, before quickly ducking back down.
Ink Demon
The player can encounter the Ink Demon if they destroy enough of his cutouts (they may also receive a voiceline from Alice Angel or if they stand still for too long (this also counts for when they player has their game paused). Additionally, holding the shift key and typing K414 will trigger the jumpscare.
Ink Rave
The Ink Rave can only be triggered one time. First, you must clench all three of the bendy glove hands, then break the popcorn sign in the theatre, drink 25 cans of bacon soup until you hear a burp (or one golden can), then you have 15 seconds to bring a can into the theatre and throw it at the Little Devil Darlin' poster, revealing a hole. Press E on the hole makes the look through the crack, the player should see Alice, Slicer, the Ink Demon, Wilson Arch, and Sammy raving.
Condemned Easter Egg
When the player boots up the game and walk to The Drawing Board before doing anything and walk up the the boards with the "Condemned" sign the player will hear the old Ink Machine sound used in the Bendy and the Ink Machine's prototype demo.
Specific Versions
In certain versions of the game, objects would appear on the large stage in the Main Hub:
- A furnace appeared first.
- In a later version, a rotating office chair appeared.
- A Bendy trash can originally seen in Storage 9 during Bendy and the Ink Machine: Chapter 4 - Colossal Wonders could be seen after the spinning chair. If a player threw 10 cans into the bin, it would start spitting out popcorn
- While not on the actual stage, the Bendy Mascot Costume originally appeared near the Teaser Room, before it was updated and it was given the "weeping angel" mechanic.
- When the Mascot Costume gained the ability to move, a group of bugs appeared on the stage for a couple versions.
