El Rubí Maldito

El Rubí Maldito (The Cursed Ruby) is a screamer video uploaded to YouTube by Maignofe on February 28th, 2017. Later, the title was changed to "☠ Screamer Rubí ☠".

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, and the horror music from earlier begins to play. At 1:08, a picture of Amy Peterson from Fright Night pops up with the same scream from SCP-450 and 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" (THE CURSED SAPPHIRE), uploaded by the same creator.
