In honor of Halloween, popular prankster Jack Vale contrived one of his spookiest pranks yet.

While on the boardwalk, Jack asked passersby to take his photo while he stood in front of a large wave collage.

What the volunteers didn’t know is that Jack’s phone was actually playing a video he made before with a spooky zombie girl walking by. Naturally, the volunteers were chilled to the bone after seeing a zombie girl walk by in the phone that didn’t exist in real life.
