El Rubí Maldito

El Rubí Maldito (The Cursed Ruby) is a screamer video uploaded to YouTube by Maignofe on February 28th, 2017, the title later changes to "Screamer Rubi"

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.

There is another screamer that is quite similar to this video called "EL ZAFIRO MALDITO", uploaded by the same creator, it shows the same ruby asset from Battle for Dream Island, but its colored blue, a picture of a zombie appears afterward.
