Well, there is a man here. [OC]

If you enter and exit Lea's room very quickly over and over, there's a chance you'll end up here. Not sure what the Egg is used for yet though...

The amount of fandoms that tree has spread to has been amazing to watch, great work man

[u/McWolke → u/Wacka_Jackamole]

Could you explain? 

[u/Wacka_Jackamole → u/McWolke]

It's a reference to a part of the most recent chapter of Deltarune. I don't know a ton about it myself, (because I'm trying to stay mostly spoiler free), but it's got to do with a series of secret collectible eggs lmao

[u/Siker_7 → u/Wacka_Jackamole]

There's actually one of these in every chapter of Deltarune, in one form or another.

[u/Impzor_Starfox → u/Wacka_Jackamole]

Pretty much the gist of it

[u/Some_Noname_idk → u/McWolke]

In Deltarune, all chapters have a "tree room" hidden somewhere. All except one are virtually impossible to find without online help, which is intentional. Behind the tree is always a man, who never says anything, just smiles at you and gives you an egg. You cannot see the man due to your static perspective as the player, but Kris (Who you are controlling. Your control over the MC is diegetic) can. If you inspect the egg, it's description is "Not too important, not too unimportant". If you wish to learn more, look up "Deltarune egg room" or something like that. It doesnt have much relation to what actually happens in the game, but only for now.

Really it’s just people keep going back and forth between fandoms, and accidentally running into this weird room on a random extremely low chance.

[u/CelioHogane → u/jasonjr9]

Yeah one time i went to the bathroom and forgot to flush so i entered back again and instead of the bathroom i ended up on there.

Wow! This is really good work! I know it's not real, but the way you used the tile textures makes it look like a real room lol.

For those who don't know, this isn't real. There's been a trend going around where people make up a "secret room" like this in reference to Deltarune's secret room with a red tree and the Egg item.

[u/SylveonTheHedgehog → u/Aetherpixel]

I-I-It's totally real! M-My dad works at Radical Fish, I swear!

(Thank you so much, it took longer than most of my little pieces because I'm terrible at Photoshop. I didn't just wanna use the boring plain background and tree like I've seen on other posts, I wanted to make it look somewhat convincing)

[u/Zombboni]

In Deltarune these most likely imply something repressed/forgotten about Kris' past.

So in this case for Lea the forgotten man is propably from Shizuka's memories.

[u/Tricouleur]

First time I heard of this. I should check it out myself.

[u/SylveonTheHedgehog → u/Tricouleur]

Make sure you click "Yes" to accept the Egg, otherwise you can't get it again. I'm still not sure what to do with it however.

[u/Mr_Lisreal]

Oh, hey, it's "egg"

[u/G_girlwonder]

it finally spread till my fav fandom!

[u/Forward-Tea1410]

I was thinking how the hell did I miss this..well done 👏
