Mermaid Tales The Black Lullaby: The Dark YouTube Series We Can’t Stop Watching

Sometimes the best finds are accidents. Over Labor Day weekend, while most people were juggling BBQ smoke and last-minute NFL fantasy drafts, we stumbled into Mermaid Tales The Black Lullaby on YouTube. We weren’t even looking for it—just clicking through recommended videos—and now we’re sitting here wondering how this series wasn’t already on our radar.


First Impressions of Mermaid Tales The Black Lullaby

Here’s the thing: we had zero context going in. No binge of season one. No deep dive into Aphmau’s giant catalog of stories. Just curiosity and a free afternoon. And honestly? That might have made it even better.

Right out the gate, the vibe feels different. Mermaid Tales The Black Lullaby isn’t just some cute, safe kids’ fantasy—this one has teeth. Literally. The first couple episodes gave us stormy seas, shady secrets, and that eerie “lullaby” humming in the background. By the time Captain Aaron was scrambling to keep his crew together, we were locked in.


What Exactly Is This Series?

After a quick search (because we had to know more), we learned that Mermaid Tales The Black Lullaby is actually season two of the Mermaid Tales saga by Aphmau. If the name rings a bell, it’s because Aphmau has been one of the biggest creators in the YouTube fantasy/roleplay lane for years.

But here’s the kicker: this season isn’t roleplay—it’s fully animated. And that animation? Crisp, moody, and perfect for the kind of ocean-bound supernatural story being told. It gives the show a bigger scale, sharper fights, and a more mature edge.


Why It Pulled Us In

Watching Mermaid Tales The Black Lullaby for the first time felt like diving into a story that had been waiting for us. A few things jumped out right away:

  • The darker tone. The swearing caught us off guard (Aphmau characters cursing? Did not have that on our bingo card), but it works. It signals that this season is here to grow with the audience, not hold back.
  • The mystery. That mermaid song isn’t just a plot detail—it feels like a living, breathing character haunting the edges of every scene.
  • The cast chemistry. Even without knowing everyone’s history, the crew—Aaron, Aphmau, Zane, Caspian, and more—feels like a dysfunctional family you immediately want to root for.
  • The world-building. You can tell this connects to Aphmau’s bigger universe (My Inner Demons, Minecraft Diaries, etc.), but even as newbies, we didn’t feel lost. It’s easy to follow and easy to theorize about.

If you’re into the mermaid and fae aesthetic, this series will hit all the right notes. And when you’re done binging, you should also check out our breakdown of Revolt World: The Blerd Experience—another magical dive into culture and creativity.


Episodes We Found So Far

Over the weekend, two episodes were available:

Episode 1 – Voices in the Deep

The chaos begins with a pirate battle at sea: a reckless captain, his crab companion, and the sudden appearance of a mermaid who rescues someone mid-fight. The crew squabbles over stabbing, shinies (treasure), and how close they are to sinking as the ship takes heavy damage. The mermaid patches things temporarily with sea sponge paste, though the crab wastes no time calling the captain reckless.

  • At Hangman’s Rest, a shady human port, the captain warns the mermaid to stay hidden while the crew debates selling a rare pearl. Naturally, the crab refuses to part with shinies.
  • Meanwhile, the mermaid explores the ocean, stumbles across a sunken ship, and finds another mermaid named Ammell, who’s been singing for help. They bond briefly before danger forces them to flee.
  • The episode closes with a tense diving contest for gold, a near-drowning, and the sense that something unseen is pulling the strings beneath the waves.

Episode 2 – Moon-Black Tears

If episode one set the stage, episode two makes things personal.

  • The mermaid shows her nurturing side, trying to feed human children fish despite warnings from the crew. The kids outsmart a pirate in a coin game, though he admits he lost on purpose so they could buy bread.
  • Aaron senses strange flashes in the water and dives in, suspecting they’re tied to Caspian. Meanwhile, the mermaid undergoes a startling transformation, temporarily gaining human legs—and struggles with new instincts and identity.
  • At the port, the crew meets Lawrence, a merchant, who warns Aaron about missing women and rumors of a phantom ship ruled by “the wolf.”
  • Caspian takes the mermaid under his wing, protective yet cautious, while she remains eager to befriend the humans. She gifts Caspian a token in innocent trust, sparking jealous tension between him and Aaron.
  • Aaron notices her fading mark and presses her on whether she’s made any dangerous deals, but she denies it.
  • Just as the crew prepares to depart, the mermaid suddenly loses her legs again, leaving the group rattled and hinting at even deeper mysteries ahead.

Both episodes run about 20–25 minutes, which makes them a perfect bite-sized binge but packed with lore and emotion.
