@@ShinyRedUmbreon toby had a few characters from deltarune even before undertale demo, he began developing deltarune in 2012 but later decided to focus on undertale And since that clam lady says you should meet susy when you see her (look for the switch version of the dialogue too) and that different image happens when you see her, it's clearly a reference to deltarune

[@thequeerishere9662]

In Sans’ side room, the music is a slowed down version of It’s Raining Somewhere Else (the song on your date with him) which itself is a slowed down version of Sans (the song that plays in the skelebros house) which itself is a slowed down remixed version of the basic melody of Song That Might Play When You Fight Sans!

Just because I'm a nerd and it's something I think about regularly, "Sans's" would be correct. Names ending in S get treated like any other. You only don't have an "s" after the apostrophe if (1) you're referring to a historical figure whose name ends in -es or -is (or if you're talking about Jesus; "Jesus' sandals," for example), (2) if something is plural ("the dogs' toy"), or (3) it's part of a saying (examples: "for conscience' sake" or "for righteousness' sake") I busted out my Elements of Style book to check. 😂

Sans’ Codewords Secret Codeword: “i’m a stupid doodoo butt” Secret Secret triple-secret Codeword: “i’m the legendary fartmaster”

[@hayaty9867]

I honestly think sans is from the dark people from deltarune who are against relsei. My first reason is because, sans can teleport. You might think I'm being silly but I'm not, lancer can also teleport as you can see in the game. My second reason is that all monsters in deltarune run away before they actually die (if you decided not to act). Sans ran away before he actually died genocide. I think he got that habbit from killing monsters in deltarune or people around him did it. My next reason is that papuryus says "when his lights are off it's like a different dimension" In deltarune when the lights were off in the storage room, The room got bigger and bigger like it was endless. Then you have sans bleeding: susie says to lancer "we all bleed right?" And he doesn't correct her because it's true and all the times they say stuff that has to do with bleeding he never corrects them. The room your in when sans say how much LOV and stuff it's the exact same symble in deltarune. Then in genocide mode he says "Take it from me kid... Sometimes you should just learn to quit." Meaning he was obviously trying to do something but it never worked. Now you might be thinking "WHAT ABOUT PAPURYUS?????" well let's be real: papuryus is pretty gulible to be real. He still believes in santa clause when really it's sans writting those letters, of course he could of just told him "Hey you are my biological brother" and papuryus would be like " OKAY VERY TRUE TRUE TRUEEE". He easily could of just found him somewhere and took him as his little brother. I have more reasons but i forgot looool. Anyways ty for reading even tho it's long 😂

In my opinion, the sad thing is that people don't realize what the backyard meant. The backyard was something that meant in sans memories... The photo was photoshopped by sans to make it look like sans was actually in it, the "Symbols" were actually blue prints for the time machine, this backyard was for sans memories. He finds his new home and really enjoys it then the other home he lived in, and he's wearing a mask, and papyrus is the real skeleton. Then, he gets really sad that his home has been ruined... no friends, siblings, and food, it's all gone. Then sans tries to stop himself from being killed as he is the only one left in the underground, he gets killed and no one else exists in the underground, and then, the human can't leave the underground
