Undertale Yellow: Pacifist Backtracking

Like in Undertale, completing an area in Undertale Yellow during the Pacifist Route will cause various enemy NPCs to appear throughout the overworld. Shop Keepers also gain new dialogue, as well as certain overworld NPCs. This video only includes back tracking content you can experience right before the game's final boss, so it doesn't include the Dark Ruins or Martlet dialogue (or Martletless dialogue in the case of Oasis Valley). And of course, no neutral content is included either.

"Before you leave, you should try hugging someone!" Line hits HARD

[@Nate2010]

BRO,

[@X-SPONGED]

Is that a reference to Frisk hugging Asriel?

[@Nate2010]

@X-SPONGED no, it's a reference to how undertale yellow ends with clover hugging martlet, starlo and ceroba

[@Elsanic57]

If only we could stay with Martlet we would have Dalv as a neighbor

[@yooostepdaddy1439]

0:34 I think this is the devs trying to say they planned/plan on adding more, but they are currently exhausted from the 7 year development, and we’ll have to wait a long time before it’s finished. He says it’s real tiring to mine the boulder (make the game) and we should be patient.

[@juu4503]

I think its gonna be the same with the girlboss cactus

[@emidemi7211]

I'm not sure if they're 'trying' to say anything. I suspect they're just one-off jokes. An update that adds some new side content would be pretty cool though.

[@X-SPONGED]

24:50 I love that the devs put so many references about the game's development into the game itself. None as obvious as the sapling. Literal years of hard work finally blossoming into UTY. Really hope this game inspires more people to make similar ones with the same level of quality.

[@HypaBeast]

you ringing the bell in time to the music at 13:00 was fucking adorable

[@featuringdantefromthedevil9749]

I love the little speech penilla gives

[@Xiang_Lance_Dark]

4:48 I think Dalv have some vere little sense about the RESETS, but he seems like not to care about it much

[@ClodsireBcuzYes]

DUDE ISTG I SAW DALV'S LETTER AND REALIZED: "oh, i should go see how he's doing, i forgot to last time." AND HE IS WEARING THE SWEETEST LITTLE PUFFY SWEATER EVER- THEN HE SAYS "do for them what u did for me" and "i wish you all the luck in the world!" AND I ACTUALLY CRIEDDDDD. I LOVE HIMMMMMM- HE LOOKED LIKE A LITTLE SWEET BABY WHILE HOLDING POPS- I WOULD DIE FOR DALV I SWEARRRR oh and, dalv going to play the piano in the credits made me cry but i was already crying so- bro i love dalv so much why do people not like him, he is the sweetest little babie

algorithm boost, these are lovely and underrated even in the original game

[@epl_500]

wow Virgil turned out to be a pretty good guy!

[@stellarrev9833]

axis already wanting to be a parent (to his OWN child no less) is hilarious considering just a few hours ago he tried to vaporize clover how would that even work? he builds one out of his own + daisy's image? probly

Algorithm comment Also Dalv in that big poofie coat gives me life i love this goober

[@RabbitKetsukane]

Can you do neutral route backtracking, preferably where Star dies? Interested in seeing where Ceroba ends up at if at all since she may just disappear.

[@lazy.0]

I think she disappeared but the gang is at the bar playing music

[@Plantify9339]

@@lazy.0only if Starlo is alive

[@lazy.0]

@@Plantify9339 OH YEAH HUH if you kill something in the "core" of this game

[@TheDuckyDino]

If I make a neutral video it’ll probably be about differences in the neutral route in general

[@TheoDimitry]

After star dies Ceroba will ask you about his whereabouts and then she'll go to check his house.

[@hecate7]

You technically missed one. Despite being innaccessible, the chef enemy from the Steamworks has some dialougue in the pacifist route, like the other bots. He explains that his French accent is because monsters used to have similar accents like humans throughout the world, before getting sealed underground. I know you can't access him, but it's cool this dialougue exists.

[@TheDuckyDino]

That’s Neutral backtracking, not Pacifist Backtracking.

[@hecate7]

@@TheDuckyDino Really? I thought enemy npcs didn't spawn in the neutral route, but I never bothered checking, so I may be wrong.

[@TheDuckyDino]

@@hecate7 you can only encounter Sousbourg in the neutral route, so it would literally be impossible to encounter him otherwise. Enemy’s will appear in the overworld as long as you didn’t kill any in their area, so he appears if you spare every enemy in Steamworks after killing at least one in a prior area.

[@misk-ivus2990]

Thank you for making this, I missed all the steamworks bots on my playthrough.

Does the monster appear if you spare them by shooting first?

[@TheDuckyDino]

Yes, they’ll appear as long as you didn’t kill one or more of the monsters in their area

is this fan made or does this actually happen

[@TheDuckyDino]

What do you mean? UTY is a fan game but everything in this video is footage from the game

[@user-vm6mx6ht9b]

@@TheDuckyDino i mean the spared enemy encounters on the overworld, i've only seen dalv but not the rest after double checking the other zones

[@TheDuckyDino]

@@user-vm6mx6ht9b this is all from the actual game. Not sure why they didn’t appear for you.
