Unknown Sound in clip

Unknown Sound in clip is a screamer video created and posted onto YouTube by a user ThePopUpVideos in May 8, 2010.

The video begins with Windows Movie Maker on a red background, with a top grey box and the text "Track 4206#" at the top. Following that, the text advises the viewer to turn up the volume "because" the music is indeed silent, and the viewer can now hear the soundtrack's introduction. After that, the text appears, slowly typing, instructing the viewer to pay close attention.

However, the sentence is interrupted by a demon child from Dead Birds with the same scream from Where's Waldo?.
