I have an idea for the "Egg" Guy, specifically, the 'good thing.'
After collecting all the eggs, the player will receive an item called the "Egg Scrambler." This item, when used, will walk to a classroom that has an uncollected notebook in it. When it reaches its destination, it will mark its location to the player, even through walls. After the player collects the notebook, it will blow up and despawn.
Alternatively, if all notebooks have been collected, it will instead seek for Baldi, and once he reaches him, it will blow up right in front of his very own body, causing him to use his shrink machine sprite from BBCR as he gets stunned for about 30 seconds.
