What Is the MC-373144 Error in Minecraft?

Minecraft is no longer just a computer and console game—it has also become part of modern popular culture. For more than a decade, players have created countless memes, stories, and urban legends around the game. Sometimes, an obscure error or glitch can prompt players to investigate and become the basis for a new legend.

YouTube channel Wifies recently published a feature-length video discussing “Leviathan” sightings circulating on social media. What exactly is MC-373144? Can it really cause a giant Leviathan to appear in the oceans of the blocky world? The answer is far less mysterious than the rumors suggest.

What Exactly Is the MC-373144 Error?

If you want the short answer, MC-373144 is not a real error code in Minecraft. Instead, it is a fictional premise created by YouTuber Wifies for the video. No such giant creature exists in the game's oceans, and players will never find the so-called Leviathan, no matter how long they explore.

However, the video built around this premise is genuinely fascinating. Running for more than an hour, it begins by carefully establishing the story and building suspense. Wifies starts investigating after searching for MC-373144 and the Leviathan, attempting to figure out what this error is and what kind of creature it might have spawned.

During the investigation, Wifies encounters a character named Hummer. Hummer claims to know about the Leviathan and how players are supposed to find it. Wifies then explores several worlds and servers, gradually tracing the rumors surrounding the creature and attempting to reconstruct what supposedly happened behind the glitch. At the time of writing, the video had already surpassed two million views.

By the end of the exploration, Wifies still had not actually found the Leviathan, but that was not the end of the story. He eventually entered a strange area where a massive castle was floating, and the castle's appearance also interfered with the game's recording.

After entering the castle, Wifies discovered a chest. It contained no rare equipment and no explanation of the Leviathan—only a Heart of the Sea.

Wifies ultimately concluded that most of the Leviathan legend had been fabricated, although he had indeed encountered something he could not explain. The video ends with him sending an email to Hummer. He promises to continue investigating to find out what the Leviathan really is, hoping that he and Hummer will eventually find the answers.
