Where to Put the Egg in Deltarune (Chapter 3)?
Written by Aarav Agarwal
After getting the egg in Chapter 3, it shows up in your key items. But the second you return to the Light World (between chapter 3 and 4), it vanishes from your inventory.
This is normal and happens to everyone… As far as we know.
Can You Use the Egg?
No one’s figured that out yet.
There’s no way to use it in combat or dialogue, and it doesn’t trigger any events. The Egg disappears before you return to anywhere it could possibly matter.
It might come up in a later chapter... or, perhaps, not. If/when we figure that out, though, we’ll update that here.
Can You Miss the Egg?
Yes, very easily
The Egg in chapter 3 can be found here. If you beat the Shadow Mantle fight too soon, you lose access to the TV rooms tied to the puzzle.
If you’re going for it, make a backup save early.
Final Blurb
You grab the Egg, it disappears, and the game says nothing about it. That’s the whole story... for now. Whether it becomes important later or is just a weird collectible, nobody has the answer yet.
It’s Deltarune. It’s supposed to be confusing.
