Notebooks

Notebooks (misspelled in the How to Play section as Noteboos) are the main objective in Baldi's Basics in a Bunch of Shet and supposedly belong to the Protagonist's friend.

Story Mode
Touching the first notebook will open The Lorax, which prompts the first 3 normal math problems that are possible to solve. However, touching other notebooks will bring up the same pad, except an unsolvable, corrupted math problem as the third and last question.

When the player eventually collects all seven notebooks (so long as if they get 6 questions wrong), Baldi will become extremely fast (a bit faster than the Player's sprinting speed) and rush at the Player. At this time Arts and Crafters will also become a new threat to the player.

The new objective is to then find an exit and finish the game when all 7 notebooks are obtained, unless the player is playing Endless Mode.

Endless
When playing in Endless Mode, there is no limit to the notebooks you collect. After a certain amount of time, the notebooks will respawn in random rooms, and a chime plays to notify you of their presence. If the player finds a notebook in this mode, the unsolvable math problems (aside from the 2nd notebook) will be solvable, but Baldi will still accelerate in speed while the player is trying to find them. When the player gets caught by Baldi, the amount of notebooks they collected is their high score for Endless if the player collected more than they did last time. (The high score is at the bottom.)
