SML: Y U DUMB? Elementary School Showcase

!!PLEASE NOTE THIS IS A WORK IN PROGRESS!! A showcase of the well-known school classroom from SML, first appearing in very late 2016, still being used today. I tried to find every single poster used in the "SML Movie: First Day Of School!" video (as this game is based entirely on that video's version of the classroom) but I am unfortunately missing a few. If you found one of the posters present in said video, please contact me in the group's forums.
