There is a cool glitch you can do where all the names of penguins disappear on your screen. I read about it on SecretPenguin’s site and I tried it. It is cool. You have to be a member and you have to have the portal box though.
P.S. you can go from place to place with your map and there are still no penguin names so it works everywhere not just in the box dimension. But you have to go there first through the portal to make it work.
