The child followed Toriel through a variety of areas and conquered several incredibly simple puzzles until Toriel had to leave on undisclosed business after walking down a long hallway. The child complied after receiving a phone, but less than a minute after waiting, they grew bored and went off after her.

The rest of the Ruins were filled with even more puzzles, and on their journey, the kid acquired a piece of candy as a form of healing. They also encountered a very sad ghost and cheered them up, and they met the same ghost later on after finding a ribbon to replace the bandage on the human's knee. From what they could tell, it would allow them to take attacks a bit better.

While walking along, the human thought that they saw Flowey pop up behind them, but when they wen to investigate, nobody came. They assumed that they were just seeing things and continued on their merry little way.

Several encounters, a mouse hole, the purchase of a doughnut, and the replacement of a stick with a toy knife later, and the child came across a large tree with fallen leaves strewn around it. When they approached the tree, Toriel came out from around it and immediately tended to the child before directing them into her cozy little home, and then to their own room. The human wondered what they would need their own room for if they were just doing a little detour before making their way back to the surface. Nevertheless, the bed looked quite comfy, and they soon fell asleep in such a soft place. When they woke up, there was a single slice of butterscotch-cinnamon pie in front of them. They wondered how they were going to take such a large piece of food with them, but when they picked it up, the pie seemed to vanish into their magical inventory with the piece of candy, stick, doughnut, and bandage.

After waking up, the human walked around the house and stumbled upon a mirror, and they were quite shocked with what they saw. They looked a lot like Toriel, but smaller, rounder, and much more cute. They concluded that they had been brought back as a child version whatever kind of species Toriel was.

Seeing all there was to see, the kid walked over to Toriel and asked her to go home.

Toriel's eyes widened for a moment before she put on a faux smile for the human. "Oh dear. But... this is your home!"

The child asked how to leave the Ruins.

"Ah... would you perhaps like to hear a snail fact? Here's one: Some snails have been known to hibernate when it becomes cold outside! Interesting."

The human firmly asked to go home, and after doing so, Toriel left the room to go do something. This was more than suspicious, so the kid went to follow her down the basement, which was much larger than expected. There, Toriel warned them of the dangers of leaving. According to her, they would die like every other human, only they'd die much quicker because of their rarity and how valuable their Soul was. A person named Asgore would kill them and take their Soul. Apparently, this happened more than once.

The child was adamant about returning to the surface. Although they couldn't remember much of what their life was like before they fell, they must have had some sort of life up there, right? Or, was leaving foolish since their possible family wouldn't accept them as a monster? After all, the monster must have been sealed underground for a reason. Still, they had to leave. They were determined to get out and as far away from where they fell as possible.

At last, they reached the end of the purple hallway. Behind Toriel was a door to the exit, and the only thing keeping the kid from going through was a mother's instinct to protect.

"Please go upstairs now, my child," Toriel said in a soft, melancholy tone. "It is not safe out there. You will die."

The human shook their head and demanded to leave, telling Toriel that they weren't going to fight her, and that they'd see her again.

Toriel laughed quietly. "You say that you shall come back, but that is what they all said. No, you will not. So go upstairs."

It seemed as if persuading Toriel to let them leave was out of the question. She wasn't budging from her spot, and there was no way such a small creature could move her. So, what could be done?

The fallen creature told Toriel that she had no right to keep them there. Whether she was keeping them safe or not didn't matter, because as a being with freewill, they had the right to go wherever they pleased.

"I... I suppose..." Toriel sighed and stepped out of the way. For a second, the human couldn't believe that their words worked on her. "You are right. It is wrong for me to keep you here. Just... promise me that you will not let Asgore take your Soul."

The child nodded and gave Toriel a big hug before going on their way. They felt their heart ache slightly because of the way they left Toriel. She was just trying to protect them, but even so, they couldn't stay there until they died. They ad to get to the surface where they belonged.

At the end of the path they walked, the human stumbled upon a familiar face. it was none other than Flowey the flower, who was the first creature to harm human. Because of this, they were skeptical of his appearance.

"Well well well. You must think you're real smart, huh?" Flowey asked rhetorically. "In this world, it's KILL or BE killed. You know this already, Chara. I saw you spare each and every one of those monsters and the ghost. I heard you persuade your way into leaving the old lady behind. But guess what? Not everything can be solved by friendly conversation like that mindless dummy. Soon enough, you'll come across a relentless killer. And then what? You'll die. You'll die until you tire of this world and let me gain control of it. Or, you'll just reset a few times until you get it just right. But even then... creatures like me... our minds cannot be changed."

Flowey laughed at Chara before vanishing into the ground. What he said couldn't be completely true, right? Even the most horrible creatures could have a forgiving heart, couldn't they? Or... was Flowey different?

Despite all this, the human-turned-monster went on their way through the underground. Surely their quest would be full of dangers, but they knew it wasn't anything they couldn't handle. After all, they were mostly monster, so other monsters would certainly have a soft-spot in their hearts for the child. But, none of this could be confirmed until they left the Ruins.
