In the remastered version, the Dark Energy Blaster is renamed as the 'Dark Energy Bomb'.According to Puff back in 2013, he made this as a moment of silence. This is the only fail in the entire series that lacks a fail message and audio.
It was probably designed to be used in only the most extreme of situations because it would pose a threat to those who are not even involved in the chaos. PuffBalls replying to a review, mentioning the blank message was made as a 'Moment of Silence'.
