how to get it: first go into watermelon room (behind blue recycle bin) (with a vent) and break the table, then go into one of the very corners of the map, and last but not least, open the door. (THE ROOM HAS A TELEPORTING BOX SO DONT GO IN IT BECAUSE ITS A WASTE OF YOUR TIME AND UHH UHH) and it will teleport you to a baseplate.
