A green screen that Barney
will give you if you are mean to him, or he does something that he wasn't supposed to do, in which you get when the computer crashes, thus you must manually restart your computer, also if Barney does something and it was his fault you received a green screen of death, instead of the normal mad Barney pointing his arrow at the message telling you that you need to restart your computer, he
will point his arrow at the reason why it crashed, and he
will be shocked, and there
will be a note from Barney explaining to you what happened, and there
will be an item or video thumbnail that cause the computer to crash with a
red prohibition sign on it, and he
will tell you that you may need to install something to prevent this from happening again, preferably a driver or antivirus, and may even restart your computer for you.
