El Rubí Maldito
The video starts by showing the asset of Ruby, a character from the online animated web series Battle for Dream Island, with horror music playing; however, after one second, the video suddenly switches to a puppet face while a female scream plays. 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 from SCP-450; the video then switches back to the ruby while "Monkeys Spinning Monkeys" plays.
NOTE: The following video contains a screamer!
