As part of a promotion for an upcoming horror film, pranksters put an animatronic devil baby in an unattended, remote-controlled stroller.
As people approached, lured in by the sound of a baby crying, the demonic infant would pop up while screaming. The baby also makes vulgar hand gestures and projectile vomits.
The prank was captured with hidden cameras and uploaded to YouTube. It's already racked up more than 12 million views.
The video is a promotion for the upcoming horror movie "Devil's Due."
