You're wandering through the Forest in Deltarune. You’ve beaten the puzzles, dodged the bullets, and you're just soaking in that weird, synth-heavy atmosphere Toby Fox is so good at creating. Then, you find a glitch. Or what looks like one. Between two specific rooms, there’s a tiny, frame-perfect chance to slip into a place that shouldn't exist. A silent room with a single tree. Behind that tree? A man. And that man gives you an egg.
The Deltarune Chapter 1 egg isn't just a quirky collectible. It’s a rabbit hole. Since the game dropped back in 2018, this one item has fueled more sleepless nights on Reddit and Discord than almost anything else in the game, except maybe the identity of the Knight. It’s useless. It’s cryptic. It doesn't even have a description that makes sense. But if you know Toby Fox, you know that "useless" is usually a mask for something much bigger.
How You Actually Get the Deltarune Chapter 1 Egg
Most players will finish Chapter 1 and never even know this room exists. It’s not on the main path. To find it, you have to be obsessive.
Specifically, you’re looking for the transition between the area with the Birdley-style puzzles and the deeper forest. There’s a screen transition where, if you walk back and forth repeatedly, there is a small probability—roughly a 1 in 40 or 2.5% chance—that the game will load "room_man" instead of the normal forest path.

It’s an eerie shift. The music cuts out. The screen is mostly empty except for a single, lonely tree in the center. If you interact with the area behind the tree, a text box appears. It tells you "He" is there. He gives you something. You check your inventory, and there it is: an Egg. The description simply reads: "Not too important, not too unimportant."
That’s it. No epic cutscene. No boss fight. Just a silent exchange in a room that feels like it’s leaking out of the game's code.
The "Man" Behind the Tree
Who is "He"? The game never shows a sprite. You don't see a face. But the community has some very loud theories. The most popular candidate is W.D. Gaster, the shattered scientist from Undertale. Why? Because the room’s internal name and the way it bypasses normal game logic feel exactly like the "Gaster followers" or the "Sound Test" room from Fox’s previous work.
Others think it might be a new character entirely. Some fans have pointed out that the man's dialogue is formatted in a way that feels different from the rest of the game's quirky cast. It’s cold. It’s direct. It feels like someone who knows they are in a simulation.
What Does the Egg Actually Do?
In Chapter 1, the egg does absolutely nothing. You can’t eat it. You can’t use it in battle. If you try to use it, the game just says "You put the Egg away." It’s a dead end.
But things get weird when you carry that save file over to Chapter 2.
If you managed to snag the Deltarune Chapter 1 egg, you can take it to Asriel’s room in the Light World. Or, more interestingly, you can put it in Sans’s grocery store. There’s a small egg carton in the back of the shop. If you interact with it while holding the egg, Kris will place it inside.
Now there are two.
Wait. Two?

Yeah. Because there’s another egg in Chapter 2. By repeating a similar "room glitch" process in the Cyber World (specifically the trash zone area), you can find the Man behind the tree again. He gives you another egg. When you put both in the carton, Sans's dialogue doesn't really change much, but the game remembers.
The Mystery of the Fridge
There’s also the interaction in the Light World. If you go to the hospital and check the sink or the fridge, or check the fridge in Kris’s own house, the egg has a strange habit of multiplying. In some playthroughs, checking the fridge will trigger a message saying "There are two eggs in the fridge."
This has led to the "Egg Theory," which suggests that the eggs are being used to track timelines or "shadow" versions of the world. Because the eggs exist in both the Dark World (as items) and the Light World (as reality), they are one of the few things that cross the border without turning into a pile of junk or a toy.
Why the Fanbase is Obsessed
It’s about the "Who."
Toby Fox is a master of the "breadcrumb" style of storytelling. He gives you just enough to know that something is happening under the surface, but never enough to see the whole picture. The Deltarune Chapter 1 egg is the ultimate breadcrumb.
Consider the "Wingdings" connection. In Undertale, Gaster is linked to the Wingdings font. In the game's code and certain hidden files, the move sets for characters or the layout of certain rooms seem to follow patterns that look like chess moves.
In chess, what happens when a pawn reaches the other side of the board? It promotes. It becomes something powerful. Some fans think the eggs are pawns. If we get an egg in every chapter—seven chapters in total—what happens at the end? Do they hatch? Do they "promote" Kris into something else? Or are they just a massive prank by a developer who knows we over-analyze everything?
Honestly, both are equally likely.
Comparing the Eggs: Chapter 1 vs. Chapter 2
| Feature | Chapter 1 Egg | Chapter 2 Egg |
|---|---|---|
| Location | The Forest (Tree Room) | Cyber World (Trash Zone) |
| Chance of Appearing | Low (approx. 2%) | Low (approx. 2%) |
| Interaction | Behind the tree | Behind the tree |
| Light World Use | Sans's Grocery / Fridge | Sans's Grocery / Fridge |
| Description | Not too important... | (Same) |
The symmetry is what kills people. It’s not a one-off joke. It’s a pattern. And in game design, patterns are intentional.
Common Misconceptions About the Egg
Let's clear some stuff up because there’s a lot of misinformation floating around on TikTok and YouTube "theory" shorts.
- You don't need a specific Fun Value: Unlike Undertale, where your "Fun" stat determined if you saw Gaster, the Deltarune Chapter 1 egg is purely about RNG (Random Number Generation) while moving between rooms. You don't need to edit your save file to see it.
- It’s not a "Glitch": While it looks like one, the room is fully programmed with unique text and triggers. It’s a "hidden feature," not a bug.
- The Egg isn't "The Knight": I’ve seen some wild theories that the egg is actually the Knight's soul or something. Look, it’s an egg. It might be connected to the Knight or Gaster, but the item itself is just an item. Probably.
Theories That Actually Hold Water
If you spend enough time in the r/Deltarune salt mines, you'll find a few theories that actually make sense.
One is the Trans-dimensional Theory. In Deltarune, when you go from the Light World to the Dark World, your items change. A pencil becomes a sword. A ball of lint becomes... well, a ball of lint. But the egg stays an egg. It is one of the only objects that maintains its physical form and identity across both worlds. This suggests the egg originates from a place that is "outside" both worlds—perhaps the "void" where Gaster is said to reside.
Then there’s the Easter Egg Meta-Joke. "Easter Egg" is literally the term for a hidden secret in a game. Toby Fox giving you a literal egg as a hidden secret is exactly the kind of dad-joke humor he loves. It’s possible the egg's only purpose is to be a literal "Easter Egg."
But then again, why the hospital? Why the fridge? Why does the game keep track of how many you have in your save file?
Expert Tips for Egg Hunting
If you're trying to get the egg yourself, don't just mash the arrow keys.
- Find the "Seam": In Chapter 1, go to the room right before the Great Board (where the checkerboard tiles are).
- The Back-and-Forth: Move between the room with the "Area 5" sign and the room to the left. Just keep walking left, then right, then left.
- Watch the Music: You’ll know you’ve hit it when the music stops instantly. The silence is your cue.
- Check Behind the Tree: Don't just stand there. Walk "into" the tree at the top.
If you've already finished Chapter 1 and didn't get it, you'll have to restart or use a save editor. The game checks for the egg at the start of Chapter 2 to determine if the "Egg Count" variable increments.

What This Means for Chapter 3 and Beyond
With Chapter 3, 4, and 5 on the horizon, the Deltarune Chapter 1 egg is about to become relevant again. We can almost guarantee there will be a hidden "Man" room in the upcoming Chapters.
If we find an egg in the TV-themed world of Chapter 3, and another in whatever Chapter 4 brings, the grocery store carton will slowly fill up. There are five slots left in that carton. There are five chapters left in the game.
The math is too perfect to ignore.
Actionable Next Steps for Players
If you want to be ready for the next release, here is what you should do:
- Verified Save File: Make sure you have a "Clean" save file where you have collected the egg in both Chapter 1 and Chapter 2.
- The Sans Interaction: Go to Sans's shop in the Light World at the end of Chapter 2. Put your eggs in the carton. This seems to be the "flag" that the game uses to track your progress, rather than just having it in your inventory.
- Check the Hospital: Visit the hospital in the Light World and check the sink. See if the "Egg" dialogue triggers for you. It’s a good way to verify your save is flagged correctly.
- Keep an Eye on the Trees: In every new chapter, look for "transition rooms"—areas where two screens connect with nothing but a straight path. These are the prime candidates for the "Man" room.
The mystery of the egg is a slow burn. It's a testament to Toby Fox's ability to make a single pixelated oval the most talked-about item in a game full of magic swords and goat princes. Whether it's a key to the game's ending or just a long-running gag about breakfast, you definitely don't want to leave it behind.
Go get your egg. Just in case.
