The weird ending

One of the three endings, to get it you will need to get every tag (100 in total) and go to King Eye's shipping crate, where you will find his blindfold and put it on, after that you will rip out your eyes and start the trip sequence, while "Eyes Out" plays, after that a crown will fall on a black bacground, which you "collect" by pressing any button. After it the Credits play.
