An overwhelming sense of fear washed over him.

Kenny ran away from the M cave without getting any proof of it, which is important because other commenters responded with one of the internet's favorite phrases, pics or it didn't happen.

Egged on, Kenny and his vlogging camera went back to the Mojave Desert.

Kenny retraced his steps to the vibrating cave, detailing the adventure with wide-eyed positivity.

He then uploaded the hike to YouTube on October 18th, 2014.

Yet to the viewer's dismay, the video ends with him unable to find it.

It just wasn't there.

If you watch Kenny's videos, you can sense his overwhelming good-natured spirit.

I'm sure he was disappointed to let his viewers down, so he promised to go back and try again.

His followers were excited, hoping they could see this mysterious cave.

But one user wasn't as excited.

In a now deleted comment, they wrote, quote, no, do not go back there.

If you find that cave entrance, don't go in.

If you do, you won't get out.

It's unknown if Kenny saw this ominous comment.

If he did, he may have brushed it aside as a troll.

In either case, in November 2014, he set out to find the M Cave once again.

But a new M Cave video was never posted because Kenny was never seen again.

Search teams, tracker dogs, a helicopter, all stops were pulled to find Kenny, but the dogs couldn't even find his scent.

No trace of an animal attack or any kind of foul play either.
