(Y/N) POV

Daddy was busy with Uncle Error. I hate it when he won't let me work with him. I looked at the picture that I stole from Uncle Fell. It was of a girl in a black and red sweater. He calls her Frisk. Daddy has a Frisk too, he says that if I ever saw her or her friends to tell him. I turned away and started to play with my "dolls." They are really just cardboard I made to look like Daddy and Uncle Error. The others look like the Star Sanses, Frisk Dream, and Ink. I always pretend that Daddy and Uncle Error throw the Star Sanses off a cliff, along with uncle Cross, Shhh he doesn't know. I was playing for a long time until I heard a tap on my window. I looked outside to see a Sans but he looked different than the others I've seen. He looked more like a Papyrus than a Sans. He had a blue scarf wrapped around his neck and he looked so bubbly.

"Hiya! My names Blueberry whats yours?" He asked me. I slowly climbed down the castle to talk with him.

"(Y-y/n) I looked at him, he looked nice. I was starting to get cold so I zipped up my sleeveless jacket. I watched him as he talked to me about his universe when suddenly I realized I didn't know where I was or how to get back to the castle. I began to cry.

"Hey, hey. It's ok I know your dad you can just come stay with me and my friends until he comes, ok?" He smiled. I nodded and followed him.

~Meanwhile in-

Nightmare POV
"Where is she!?" I had gone to check on my princess a few hours ago and she was gone. I have Error, Cross, and Fell all out looking for her but none of them have found her. Suddenly My brothers little group decides to show up. I glared at them.

"Not. Now. I'm busy, go play pretend heros somewhere else." I went back to using my magis to check all of (Y/N)'s favorite universes.

"Oh, we not playing around this time, Nightmare. Surrender or your precious kid gets hurt." Ink stepped foreword. He used his magic and showed me my little girl with Blueberry. I felt my blood boil.

"And they call me the monster! How could you do that? How could you even think about harming her?! She's SIX! You have no right to hurt her!" I could feel my overprotectiveness kick, but in this moment, I don't think it's being over protective.

"Then you'll surrender, and stop trying to take over the multiverse?" Frisk stepped forward.

"If I surrender, she gets to come home right? You won't harm a hair on her head right?" Only Dream nodded but that was enough for me.

"Fine, I won't take over the multiverse." Ink smirked.

"And we'll keep (Y/N) just for assurance." Ink said as they telported away. My anger exploded. I don't understand why everyone loves the Star Sanses so much, they are the villians, the kidnapped my child. I will save her. No matter what.

(Y/N) POV

I was having so much fun. Blueberry introduced me to Taffy and his Papyrus. Along with a few other Sanses I didn't even know exsisted. I liked Geno and G! Sans. They were fun.

"Hey, you're starting to look really tired. You want to go back to my house? Papy would probably be ok with a sleepover." Blue looked up at me. He was carrying me on his shoulders.

"Yea. I really want to take a nap." He smiles and we go to his house. When he sets me down, I realized that I couldn't take a nap. I was missing Kitty. Kitty was Daddy's baby gaster blaster and she always slept with me. I could never sleep without her.

"Blue?" I peeked in his room. He looked up from his battle plans. They were good plans too! I liked how much he used the blue attack, that one was always my favorite one to train with.

"Yea?" He asked.

"I can't sleep.... I need Kitty." He looked at me confused. And stood up and walked over to me.

"Kitty?" He asked me. I nodded.

"She's Daddy's baby gaster blaster. She always slept with me. I can't sleep without her."

Blueberry POV (Oh no! >:))

She's so smart for a 6 year old but what am I supposed to do? I can't make Nightmares gaster blasters...

"Oh, Ok How about you go try to sleep with Papy and I'll see if I can get Kitty, Ok?" She smiled and nodded. I gave her a hug and she walked to Papy's room. I lock my door and call Ink.

"Blue? What's up?" He asked

"Ok, so we have a slight, mini, itsy-bitsy, tiny problem." I laugh nervously.

"And that would be?" He asked. I took a minute to respond.

"Ya know how you said to let her fall asleep and then bring her to the base?" I said. I could hear the annoyance coming from him.

"Yes." He sounds really Irritated.

"She can't sleep without a baby gaster blaster that her dad has." Ink hung up. I hope he has a plan.

Nightmare POV

Ink made a huge mistake. A mistake that I thought a Sans could never make. He took one of my gaster blasters. Now I can find my baby girl.

~It's a magical time skip flying through the sky! (SHOOT IT DOWN!)

I found her and it's time to strike. Iknock on the door. Forward I know but if I know my baby girl she will reconize that knock pattern.

"DADDY!" I hear from inside. The door flies open with my baby girl standing on the other side.

"Princess!" I pick her up and she hugs me.

"I was so worried." I told her. She just smiled.

"Sorry, Daddy." She hugged me again. I looked at Ink.

"Don't ever lay a finger on my princess again." I spoke in my threatening tone. I chuckled and right before I teleported away.

"By the way, consider the surrender, cancelled." With that we left.
