you can, you just gotta find the spot you can go through O:
unless your talking about the area completely surrounded by tall fence, then you need to use the trach cans to teleport in there, all the trash cans have a random generator so you just essentially need to try til you get in, it can either be the first try or upwards of the 15th+, ifs just luck based but youll get in there if you keep trying!
idk if youve played yume nikki, but its similar to a part where you click on hat and scarfs and it teleports you around randomly til you find the right area
