"See that Soul? That's the very culmination of your being! It's a little weak now, but it can grow with LOVE."
"Now, to make your LOVE grow, you need to touch these little… White… "Friendliness Pellets".
Why did this seem so similar..? The words felt old, and annoying… As if he had used them many, many times before. As if they had grown a new meaning.
"Here, collect as many as you can!"
He summoned the bullets, making the Little Knight flinch. They quickly grabbed their stick, dodging the Bullets as they slowly approached. As Flowey tried to speak, a white slash grazed by his face, narrowly missing, almost ending his life right there. He yelped before ducking under the ground, dodging what would be a fatal attack. Seems like this kid knew what those "Pellets" really were… But how? If they were from the surface world, and they likely were, they shouldn't have experienced magic before… So how did they know? Before they could think of an answer, the Knight had managed to dig through the ground enough to see a little yellow petal. They slashed again, just for flowey to tunnel to the right and (Narrowly) Avoid the attack once more.
"Alright, ALRIGHT, I GET IT! You know what Bullets are! Just let me have your SOUL already!"
Before they knew it, they were surrounded by white bullets. The Little Knight looked around, but unlike all the other foes they had faced, there was nowhere to flee. They were surrounded.
"Jeez… What a struggle. You almost took off one of my petals! I suppose you already know my motto. It must be pretty brutal up there. . ."
A sick smile formed on their face, eyes becoming bloodshot and borderline insane.
"Don't worry. You won't see that place again. In fact, you won't have to see anything ever again! DIE!"
The flower's laughter echoed through the empty room, making the little knight shiver. As the little bullets slowly closed in on him, he panicked, backing up just to almost get hit with more. They frantically looked around, searching for any way to avoid this fate.
The little one closed their eyes, sure that this was it. That it was all over.

Nothing happened.
A moment passed, before the flower's laughter slowed, and eventually stopped. They were confused, so they hesitantly opened one eye.
The flower was just as confused as they were. Though that confusion quickly turned into fear when they felt the heat of a new flame appear. It rushed the flower, making them yelp and retreat.

"What a miserable creature, torturing such a poor, innocent youth… Do not be afraid, little one. It is alright now…"
The fire manipulating monster crouched down, looking to the "Young one". What an odd little child they were, though they were a little bit taller, with the mask that they were wearing.
"I am Toriel, caretaker of the ruins. I pass by every day to see if anyone has fallen down, and to take care of the flowers. You are the first human to come in a long while." The Goat Woman said. Her ears hung down from her head just like the Monster Child's, and their colors matched. The little horns on her head looked dull, but tough. Her paws were large, but seemed soft…
"Please, come with me. I will guide you through the Catacombs."
She started walking away, leaving the Knight more confused than before. Where were they? Who were these bugs? And what were they saying, it was no language they knew.
"Child…? Please, come with me."
She spoke again, making the Knight tilt their head in confusion.
"I suppose not…"
She sighed slightly, recognizing the new challenge this child brought. She motioned for the little one to take her hand. Finally, something he knew how to do! They took her hand, allowing her to lead them through the door.
