A teen's TikTok video showing a "secret tunnel," which he claims to have discovered inside the bathroom of his school in Honduras, has taken the Internet by storm, baffling viewers from all over the world.

The TikTok user, Eduar Melendez, posted the 10-second video on this account last week with a caption that read, "What I found in the school bathroom." The clip has so far garnered more than 29 million views.

The clip, which was recorded using a point-of-view shot, shows a bathroom stall that has a hole on one of its walls. The camera then gets closer to the said hole, which the teen calls the "secret tunnel." Inside, a piece of paper with the word "Enter" written on it can be seen. The short video abruptly ends while the camera focuses on the inside of the tunnel.

The video left the viewers curious about what could be inside the tunnel. Many of the spectators even requested Melendez to post another clip to reveal the mystery behind the hole.

Meanwhile, several viewers came up with wild theories about what could be behind the tunnel's existence.

"There's a whole secret chamber back there with LEDs and [a gaming] setup," a viewer commented.

Another person speculated that the doorway could lead to a "VIP vape club."

There was also a viewer who said it could be "the way to the anime verse or Narnia."

After getting countless requests from viewers, Melendez came up with a follow-up video titled "Part 2 of what's inside."

This time, the clip shows a little deeper into the tunnel. Its overlay reads, "there is nothing." Melendez then ends the video with footage of a "laughing" dog, leaving most viewers frightened.

The second video has so far been viewed more than 3.1 million times on the platform.

Despite several requests from the viewers, Melendez didn't climb into the tunnel. Instead, he simply reposted different versions of the second clip, adding different background music to each of them and making the viewers even more curious.

As of Tuesday, there have been no updates on what lies at the end of the tunnel, according to Washington News Today.
