Nice idea! My idea is that there will be a "more secret area" inside the school house. It provides a box of soda, and a box of zesty bars.
Then, there would be another secret area where there is a back pack, (where you gain 6 slots of inventory) and inside the box of soda and the box of zesty bars, there are 3 items in each. You would store all of the items in each box inside your back pack. If Baldi was able to calm down, whenever he gets mad, you can use the soda, and the zesty bars. So that means, after Baldi calming down, he starts rebuilding the fire. And its like another chance! If YOU know how to use the strat for this idea, you can get extra points than one try.
