How to Investigate the Mysterious Anomaly in Fortnite Chapter 6 Season 4

Fortnite has done it again — this time blending its signature Battle Royale world with the quirky charm of The Simpsons.

The event is centered on a strange new object: the Mysterious Anomaly. Here’s everything you need to know about finding and investigating it before the season wraps up.

What Is the Mysterious Anomaly?

The “Mysterious Anomaly” isn’t a random glitch in the Fortnite world — it’s a deliberate teaser for upcoming story content. The anomaly takes the form of a cel-shaded treehouse, immediately recognizable to The Simpsons fans as Bart Simpson’s iconic backyard hideout. Unlike standard Fortnite structures, it features a hand-drawn, cartoon-style texture that visually stands out from the rest of the environment.

Inside, you’ll find a small but eerie setup — a flickering TV set showing static and flashes of familiar Simpsons moments. It’s both nostalgic and unsettling, perfectly matching the tone of the Treehouse of Horrors theme that Epic Games is hinting at.

Where to Find the Mysterious Anomaly in Fortnite

To start your investigation, you’ll need to head toward Creepy Camps, located in the northwestern section of the current Battle Royale map. Once you arrive, move toward the cliffside that overlooks the ocean — that’s where you’ll spot the anomaly.

Here’s a step-by-step route to help you find it:

  1. Land or travel to Creepy Camps — it’s a well-known named location with plenty of terrain cover.
  2. Move northwest toward the cliff edge. You’ll notice a structure that looks out of place due to its cel-shaded appearance.
  3. Look for the large treehouse perched on the hill — that’s the anomaly.
  4. Approach the structure to trigger the quest progression.
  5. Climb or mantle into the treehouse for a closer look at the Easter eggs inside.

You don’t need to perform any complex actions or solve puzzles — simply getting close enough to the treehouse completes the objective.

How to Complete the “Investigate the Mysterious Anomaly” Quest

Once you reach the treehouse, Fortnite will automatically register your proximity as completing the quest. You’ll receive a 20,000 XP reward, making it a quick and worthwhile detour for players grinding the Battle Pass before the season ends.

If you’re playing in Build Mode, you can easily ramp your way up to the entrance. In Zero Build, use natural terrain or mantling to get inside the structure. Once you’re there, take a moment to observe the details — especially the TV, which periodically shows clips and static referencing The Simpsons universe.

What’s Inside the Treehouse

While there’s no loot or combat advantage here, the interior holds an interactive Easter egg that sets the tone for what’s to come. You’ll find:

  • A television screen displaying distorted images and The Simpsons references
  • Visual fragments from the animated series that occasionally appear between static
  • A deliberately nostalgic vibe that ties into Fortnite’s ongoing crossover storyline

It’s a subtle but effective teaser that rewards players for exploring and paying attention to environmental storytelling.

Pro Tips Before You Visit

  • Go early or late in a match: The area around Creepy Camps can get busy now that players are chasing XP.
  • Use Replay Mode to capture cinematic shots of the cel-shaded structure and surrounding landscape.
  • Don’t expect loot: This spot is purely for exploration and XP, not tactical advantage.
  • Finish the quest before the season ends: Once Chapter 6 Season 5 begins, the anomaly (and its XP reward) may be removed.

Investigating the Mysterious Anomaly in Fortnite is a quick but memorable quest that connects two entertainment powerhouses — Fortnite and The Simpsons. Beyond the XP, it’s a clever Easter egg that showcases Epic’s mastery of storytelling through world design.
