El Rubí Maldito

El Rubí Maldito (The Cursed Ruby) is a video uploaded to YouTube by Maignofe on February 28, 2017. The video starts by showing a ruby with horror music playing; however, after one second, the video suddenly switches to a puppet face while a female scream plays in the background. After 20 seconds, the scream stops; the video starts playing the horror music from earlier. At 1:08, A Picture Of Amy Peterson from Fright Night pops up with the same scream used in SCP-450; the video then switches back to the ruby while "Monkeys Spinning Monkeys" plays in the background.
