Unknown Sound in clip

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

The video starts with Windows Movie Maker on a red background with top grey box and text stated: "Track 4206#", After this, the text asks the viewer to turn up the volume as a recommendation "because" the music is indeed quiet, and now the viewer can hear the introduction of the sound track. after the clip, the text appears, slowly typing, telling the viewer to listen carefully.

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