Description:SCP-3006 is a video titled " we are number one except every time you play it there are twice as many robbie rottens but the room is the same size[nsfw]" which was posted to the YouTube video hosting service on October 12th 2016. It features a musical clip from the show "Lazy Town" that, on repeated playbacks, causes a number of humanoids identical to Stefán Karl Stefánsson to appear.

Videos impacted by SCP-3006 are capable of spreading their effects, primarily by being posted in threads where multiple non-affected videos are present. Within 1-5 minutes of being linked to, all other videos linked in the same thread will begin manifesting SCP-3006's effects. Humans or living humanoids featured in the video will double with each playback, including individuals who are off-screen such as cameramen and sound personnel. The effect is exponential in that, upon each playback, the number of subjects in each videos doubles. For example, a video containing 2 subjects, will instead have four upon the second playback, the third would have 8, and the 5th 32. None of these entities appear to have knowledge of SCP-3006's effect, and find it highly distressing.
