Oh noes! Your friend left all his noteboos in Baldi's Schoolhouse, but doesn't have any time to go get them, or else he'll be late to eating pracitce! That leaves you, his best friend, to go fetch them for him.

Arriving at Hereschool and walking through the yellow double-doors, you're greeted with Baldi, standing there, a smile on his face.

"Oh, hi!" He says with a wave, seeing you enter. "Welcome to my schoolhouse!"

Behind him were two blue doors, both labelled '99', assumably classrooms.
