Many years later, <a href="/wiki/Asgore" title="Asgore">Asgore</a>, the king of the monsters, has collected five of the seven human souls needed to break the barrier to the surface world. The story follows Clover, a human child with a soul embodying the trait of "justice," as they enter the Underground to investigate the disappearance of the five humans. Falling through a crack in the Ruins, they meet <a href="/wiki/Flowey" title="Flowey">Flowey</a>, a sentient flower, who teaches the player about the game's mechanics. Flowey accompanies Clover on a journey to Asgore's castle, where Clover can cross the barrier to return to the surface. </p><p>While traversing the Underground, Clover explores many new locations, including previously unseen sections of areas from <i>Undertale</i>. They encounter numerous monsters, such as Dalv, a recluse living in the Dark Ruins; Martlet, a member of the royal guard stationed in Snowdin Forest; Starlo, the sheriff of the Wild East; Ceroba, Starlo's childhood friend and the wife of a deceased scientist, Chujin; and Axis, a hostile robot residing in the Steamworks. Most monsters engage Clover in combat, giving them the choice to either fight and possibly kill them or show them mercy. </p><p>The game's story diverges based on how the player chooses to resolve battles with monsters. If the player chooses to kill some but not all of the monsters, they experience the "Neutral" ending: when Clover almost reaches Asgore's castle, Martlet offers to keep them safe in the Underground instead. However, Flowey kills her after Clover agrees. Enraged, he admits to manipulating Clover's journey to ensure they reach Asgore alive, in order to steal and absorb the human souls while Asgore is distracted. With his plan failed, he attempts to absorb Clover's soul during a nightmarish battle in his mind. However, Flowey eventually grows bored of the fight, citing Clover's refusal to surrender. Disappointed with this outcome, he decides to reset the timeline to achieve a better ending in the next run, abruptly restarting the game. </p><p>If the player chooses to spare all of the monsters, they experience the "Pacifist" ending: Ceroba discloses that her daughter Kanako has "fallen down" (a fatal condition rendering her <a href="/wiki/Coma" title="Coma">comatose</a>). She accompanies Clover through the Steamworks as a shortcut to the royal lab to investigate Kanako's situation. The two of them are interrupted by Starlo, who questions Ceroba's motives and chases her away. It is revealed that Chujin attempted to create a soul-strengthening serum using the souls of a human and a "boss monster," which Ceroba intended to perfect using Kanako's and Clover's souls. Martlet, Starlo, and Clover confront Ceroba, but she is able to overpower all of them. During the final battle against Ceroba, Clover learns that Kanako fell down after requesting that her mother test the serum on her. Ceroba obliged, but the reaction caused Kanako to fall down. Upon being defeated, Ceroba collapses in anguish and asks Clover to finish her off. </p><p>If the player kills Ceroba, Starlo will express hatred towards Clover and leaves with Ceroba's mask. Martlet escorts Clover to the castle's throne room, and the game ends with Asgore reluctantly claiming their soul in battle. If Ceroba is spared, the player experiences the "True Pacifist" ending, where she expresses remorse for her actions before reconciling with the others. After reflecting on their journey, Clover decides to sacrifice their soul to aid in the freedom of monsters. During the game's credits, Dalv, Martlet, Starlo, and Ceroba float Clover's hat and gun down a raft leading to Waterfall's garbage dump.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> Later, Clover's soul hears and answers a call for help from "someone."<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>b<span class="cite-bracket">]</span></a></sup> </p><p>If the player kills enough monsters to exhaust the kill counter for every required room of the game, they experience the "No Mercy" or "Genocide" ending. The game's tone changes significantly during this route, with the soundtrack becoming more ominous, monsters disappearing from the Overworld, and most major fights becoming more intense and difficult. Additionally, Clover exhibits increasingly aggressive and threatening behaviors as the story progresses. In the Wild East, Clover kills Starlo in a duel, followed by a vengeful Ceroba. Before they reach Asgore's castle, Martlet tries to stop them by transforming into a powerful being with a serum from the royal lab, but is defeated and killed. After the battle, Flowey accidentally reveals his desire to steal the human souls and gets shot to death by Clover. The game ends with Clover killing Asgore, freeing the human souls and escaping the barrier. </p> <div class="mw-heading mw-heading2"><h2 id="Development_and_release">Development and release</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Undertale_Yellow&action=edit&section=3" title="Edit section: Development and release"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1224211176">.mw-parser-output .quotebox{background-color:#F9F9F9;border:1px solid #aaa;box-sizing:border-box;padding:10px;font-size:88%;max-width:100%}.mw-parser-output .quotebox.floatleft{margin:.5em 1.4em .8em 0}.mw-parser-output .quotebox.floatright{margin:.5em 0 .8em 1.4em}.mw-parser-output .quotebox.centered{overflow:hidden;position:relative;margin:.5em auto .8em auto}.mw-parser-output .quotebox.floatleft span,.mw-parser-output .quotebox.floatright span{font-style:inherit}.mw-parser-output .quotebox>blockquote{margin:0;padding:0;border-left:0;font-family:inherit;font-size:inherit}.mw-parser-output .quotebox-title{text-align:center;font-size:110%;font-weight:bold}.mw-parser-output .quotebox-quote>:first-child{margin-top:0}.mw-parser-output .quotebox-quote:last-child>:last-child{margin-bottom:0}.mw-parser-output .quotebox-quote.quoted:before{font-family:"Times New Roman",serif;font-weight:bold;font-size:large;color:gray;content:" “ ";vertical-align:-45%;line-height:0}.mw-parser-output .quotebox-quote.quoted:after{font-family:"Times New Roman",serif;font-weight:bold;font-size:large;color:gray;content:" ” ";line-height:0}.mw-parser-output .quotebox .left-aligned{text-align:left}.mw-parser-output .quotebox .right-aligned{text-align:right}.mw-parser-output .quotebox .center-aligned{text-align:center}.mw-parser-output .quotebox .quote-title,.mw-parser-output .quotebox .quotebox-quote{display:block}.mw-parser-output .quotebox cite{display:block;font-style:normal}@media screen and (max-width:640px){.mw-parser-output .quotebox{width:100%!important;margin:0 0 .8em!important;float:none!important}}</style><div class="quotebox pullquote floatright" style="width:500px; ;"> <blockquote class="quotebox-quote left-aligned" style=""> <p><i>Undertale</i> has inspired many to create amazing things and it is no different here.
