Introducing 777 Appears after Dread Hollow Station (in canon Monster Metro areas) 777 can appear at anytime, even rebounding like 17, but the only catch is he's invisble and only appears as flickers for a milisecond. If you're playing with sound off this will become a probelm. After 777 appears, things can be a big probelem. Click-to-close windows will start obstructiing the screen making it annoying and hard. Drink a Energy Drink to clear things up. 777's train sound is the Windows error sound. Death screen flavor text: "777 can put annoying pop-ups on your screen after he appears! Be careful when going out of your safe place!"
