Ruins (2024)

This article is a stub and should be expanded. Please add content by editing the page.

The Ruins is the first location seen in Undertale Yellow. Clover finds themself there after falling down Mt. Ebott before the beginning of the game, and it is where they meet Toriel.

Features[]

The Ruins have not changed from its Undertale counterpart, besides the malfunctioning switch room puzzle, and an added lower level of the Ruins called the Dark Ruins. The Dark Ruins is mostly composed of large rooms, water streams, bridges, and a small cave system with no illumination.

Due to the addition of Dark Ruins, the area is far larger than what is seen in Undertale, which suggests that a larger society of monsters had developed here before moving to New Home.

Main Story[]

Toriel meets Clover after they encounter a Froggit in the second room. She then guides them through the Ruins until they reach the switch room. Clover falls through a hole that leads to the Dark Ruins due to a puzzle malfunctioning. This is because Flowey tampered with the switch due to every run ending up in Clover staying with Toriel or dying some other way.

All of the new monsters are found and fought in the Dark Ruins, including the miniboss and area boss.

Geography[]

Ruins[]

Ruins is mostly identical as seen in Undertale, the difference being that Clover can't proceed beyond the switch room.

Dark Ruins[]

The Dark Ruins is a secret lower level underneath the Ruins, which Clover accidentally enters after falling through a hole that was made by pulling the unlabeled switch in the Ruins. Puzzles in this area use different objects that can open doors, disarm spike traps, or otherwise grant Clover a passage into the next room.

The Second Switch Room[]

The second switch room is a room with three switches on the wall, spikes that prevent the protagonist from entering the next room, and a plaque on the wall that reads "EXPOSITION" in large friendly letters.

In order to proceed, the protagonist must pull the third, first, and second lever in order. If done correctly, the spikes will disappear, leading you to the next room.

The First Glowing Boxes Puzzle[]

This puzzle has five glowing boxes, with the first and the fourth glowing box turned off.

If you turn on or off any of these boxes, it will turn on / off the others at their sides. In order to complete the puzzle, the protagonist must activate the second, and then, the third glowing box. It will make all glowing boxes turn on and the protagonist can advance, leading you to the next room. If not, press the switch and the puzzle will reset.

The Second Glowing Boxes Puzzle[]

This puzzle is similar to the first glowing box puzzle, except it contains ten boxes set up in a five by two fashion.

Starting off, the first and third boxes in the first row are on, along with the second, third, fourth, and fifth boxes in the second row. To solve the puzzle and be able to proceed, one must first press the middle box in the second (The lowest row) row, then the second box in the second row, and finally the fourth box in the first row.

Corn Field[]

Upon entering the Corn Field, three paths can be observed, with two being blocked off by spikes and the last one being the entrance to a corn maze. As the player enters the maze the player will encounter Sweet Corn. The Candy Corn item be found in the corn maze by staying on the right wall as the player traverses the maze. In order to deactivate the spikes, a switch on the other size of the corn maze must be pressed. Once the switch is deactivated, the player is able to backtrack not only to the previous room, but is also able to access a new room on the top left corner of the Corn Field. This room contains Pebble Ammo.

Pillar Room[]

The pillar room contains a save point and a few pillars, one of which has been graffitied. Before the player is able to reach the save point, the player will first encounter Rorrim.

Dark Cave[]

The entrance to the Dark Cave is located in the room that appears to be a dead end after solving the final glowing boxes puzzle. The player can access the Dark Cave by removing the sheet that mimics the wall's pattern and going into the cave behind it. The player must head to the top left corner of the room relative to the camera in order to exit the room. The top right corner of the room is blocked off by rocks until the player finishes the puzzle that unlocks the secret room.

Dalv's House[]

Dalv's House blocks off the only exit to the ruins and can be accessed after the player defeats Dalv. The Sponge Cake item can be found in the fridge.

Players are able to explore all rooms in Dalv's House except for Dalv's room. His room can only be accessed if the player kills him, thus cannot be accessed at all on the Pacifist Route. His room contains his diary, which reads "Today began like every other day. I got out of bed, brushed my fangs, and had a nice bowl of corn for breakfast. Pops made a joke at Broom's expense and we all had a laugh. I put on my cloak and went out for my daily walk. I noticed another blue corn popped up in your cornfield today. I always feel bad for discarding the special corn but I can't risk getting sick. Anyways... Something interesting happened a bit later. I overheard Flier and Penilla talking about me... About us... They said they were concerned for me. They said I talk to myself. ... Penilla then chimed in and commented on my advice and gifts to you. My signs. They said you don't exist... That isn't true. You do. I know you do. You reached out to me when I needed it the most. ...Helped me cope with the past... How could they be so mean? What do they know? I don't need them. Because... Because I have you. ... It's been one year. ... I'm still waiting."

His room also contains a phonograph which plays a version of Scott Joplin's "The Entertainer," where the only instrument used is an organ.

Corn Storage[]

This room contains the Corn Dog item and a sign above the flower patch that reads "Don't step on the flowers."

Secret Room[]

A secret room can be found by interacting with the number-shaped holes in the wall that go from one to five as the player backtracks. The player must interact with all of them in numerical order to access the secret room. Number one can be found on the right side of the room directly below Dalv's House. Number two can be found in the Dark Cave. The player can find the number by first going to the very top right of the room where Clover notices that there is a path blocked by some rocks, then taking the first path that goes leftward from those rocks relative to the camera. Number three can be found on the very right side of the Pillar Room. Number four can be found on the right side the room where the player first encounters Dalv directly before walking up the stairs to follow him. Number five can be found in the room containing eight decayed pillars, which is the room right after the room where where the player first encounters Flowey. After number five is interacted with, the player should get the message "(You hear movement in the distance... An intimidating presence fills the ruins.)" After this message, the secret room is now accessible to the player. It can be found by returning to the path in the Dark Cave that was previously noted to have been blocked off by rocks. Upon traversing this path, the player will encounter Micro Froggit. After defeating them, the Golden Pear item can be found at the end of the room.

Trivia[]

• The fact that the Dark Ruins are in a state of disrepair suggests that they may have been abandoned, and left in this state for a long time.
• If the player stays in the Dark Ruins for 5 minutes, Toriel leaves a rope in the first room in the Dark Ruins that the player can climb to return to the Ruins. If the player chooses to climb the rope, the game crashes before Clover is able to re-enter the Ruins. As the game crashes, Flowey can briefly be seen winking at a random location on the screen, implying that he has reset the game in order to force Clover to continue through the Dark Ruins.
