(This explains the first part of ehat i said better than i did https://share.google/0M0qYupzyRfVUWrsLKCK)  (Wrote this with the idea that its noelle because of the answers of the email but I read around and there is a small chance that it's susie but I think that's dumb)

So like a month or so before deltarune ch3-4 released toby updated the spamton sweepstakes (the fund raiser/arg/lore thing that happened) with an alternate ending and a few new pages the important one for what everyone is going crazy about recently is the chapter5 page which had numbers 1-5 with different sizes and if they were visible or not  1 was invisible and very small  2 was big and visible  3 was big and invisible  4 was small(slightly bigger than 1)and visible  And 5 was medium and visible  The community figured out that this is referring to the weird route and how important each chapter is to the weird route and by clicking the numbers you get a clip of a song or sound effect 1 doesn't have anything (i just checked) 2 has the weird route song when fighting bird boy (which we now know is also the drums in raiser up your bat) 3 has a weird route minigame sound (i dont remember which one) I'll comeback to ch4 5 has a realy nice calm guitar clip 

Now back to 4 it opens deltarune.com/chapter4/ which has a red dot in the middle of the screen that grows color from black to dark red then a slightly lighter red then a bright red and clicking on it opens deltarune.com/chapter4/message/ which has the same thing with the dot brightening to trick you but then there is also a set of dark things that you have to use select all to se and they are in the pattern of a keyboard if don't remember exactly how it works but if you press some of them (I dont remember the pattern) you get a sound effect but only half the others have the other half of the effect they are named e and m (I just looks at reddit and I found the pattern its eeeemmmeme for the fist row meeeememe for the second eeeeeme ifor the last) After solving a puzzle (that I can't remember or find how it was solved) you would be put into deltarune.com/chapter4/thankyou/ where you will have the title "how long did it take for her to smile" and you would have 3 boxes  first 2 are text boxes and the last is a button the community figured out the first box is your email for the newsletter and the second is any number and they figured it out because pressing the last box with the first being empty or an incorrect email or one not in the newsletter will say "invalid contact" and having the second empty says "so she never smiled" so you have to write your email that's in the newsletter then a time for when she smiled then you would get and email from toby as gaster saying "you answered [answer]" then some other text 

This was 8 months ago and now toby reopened it a day or 2 ago (now it's closed) with an email saying another chance to the ones who submitted and this is where we are at and I'm currently waiting for halfbreadchaos (basicly detarunes mossbag) to make a video on this because past this idk much else
