Main gameplay

Dirty Chalk Eraser in-game.

Dirty Chalk Eraser when used.

The Dirty Chalk Eraser produces white dust clouds when used. While in the dust cloud:

  • Baldi cannot see the player.
  • Principal of the Thing cannot see the player breaking the rules, thus he cannot send them to detention.
  • Playtime will not notice the player and cannot play her jump rope minigame with them unless she sees them.
  • Arts and Crafters cannot see the player when all the notebooks are collected, and therefore he cannot charge at them while behind the dust cloud.
  • Beans cannot see the player and will not spit the bubble gum at them.
  • Mrs. Pomp cannot see the player, therefore she will not tell them to get to her class.
  • The Test cannot see them, which means the player cannot be blinded.
  • 1st Prize cannot see the player, so he will not move towards them.

After a while, the characters will in to other directions. However, there could be a chance of them wandering towards the player and seeing them, unless they are in the corner of a room.

Even if the player is in the dust cloud, if other characters head to the same chunk where the player is on, they can see and interact with them.


In the Stealthy Challenge, the player starts with their inventory completely filled with Dirty Chalk Eraser items. The Dirty Chalk Eraser, along with the Energy Flavored Zesty Bar, are one of the few items to collect and can be used to hide from the Principal of the Thing clones.
