You placed down a Portal Poster into a classroom, expecting to use the portal to switch between rooms quickly. But instead of that, it leads to a dark musty wooden room. Making your way through the portal, you see two things. The first is two chalkboards, one reading "bladder's simples in education school - scary grandma game" and the other "don't end up like me! If you make bootleg baldi games you'll be trapped in the walls of here school... forever!" The second thing is a human, with a rather long strand of light brown hair, but other than that, completely bald. He's quite tall, and wields a brown ruler. His purple shirt is one of the only things that's bright in the damp room.
He looks at you as soon as you enter, it seems he hasn't had any visitors in a while.
