Cocomelon Scary Pop Up
Cocomelon Scary Pop Up is a screamer video on YouTube uploaded on July 23, 2021 by the user CarlosCJ@.
Video
For much of the video, it is a normal presentation of a typical Cocomelon animation; more specifically, their version of the Happy Birthday Song in which Baby celebrates his birthday with various other Cocomelon characters. The video appears to then end casually with the Cocomelon logo, but it then fades to one of the zombie girls from CrazyMarc666's screamers appears with a loud, deafening scream.
