My custom map - Classroom - ROBLOX Piggy Build Mode
Enjoy it! It took me a few hours because I forgot to save a few times...
Also if you're wondering, that first room with the blue lock is the "storage" room, and the other room besides the classroom is meant to be a principal's office. I just called it Classroom because a School map already exists in Piggy. This is also WAYYYYYYY smaller.
