A/n: after Change Your Mind. This should be fun. Requested by @Doggo_Attack

You're about 6 years old and going for a walk behind your house, in the woods. You keep giggling at nothing and picking up little stones to take home, claiming there's something special about them. You always do that, making up little stories and telling them to your mum. She loves that about you and lets you have some freedom, since she knows you're a smart girl and you know how to throw rocks hard enough to protect yourself. You walk up a little hill and hear someone talking. You get low and start army crawling up the hill and hide behind the bushes. Needless to say, you watch a lot of history based movies and your mum was in the army before she got pregnant with you. She gave up almost everything for you and you know this. You take deep breaths to keep yourself calm and peak through the bushes. "I can finally let go.." a female voice says. You look at the tall, blue being and silently gasp. There's a little, light blue being beside her. "Now that i know what happened, i can finally stop grieving. And now that everything has changed, i can't even call you mine anymore." The blue giant smiles down at the little blue person.
"I-i suppose so.. my-i mean, Blue," the little one corrects herself.
"Blue.." you mutter, staring up at her. You were obviously too loud, because they start looking around.
"What was that, Pearl?"
"I-i don't know.." You crawl into the bushes to stay hidden and silent. Blue and Pearl look around until Pearl discovers you hiding in the bushes. You throw one of your rocks at her and it hits her straight in the face. "Ah!!" She falls back and rubs her face.
"Pearl, what happened?"
"A small human threw something at me!" Blue walks over and moves the bushes aside to see you. You throw another rock, but it misses.
"Retreat!" you shout and stand up, leaves and sticks stuck in you (h/l) (h/c) hair. There's dirt covering your (s/c) skin and clothes. You begin to run away, but she picks you up by your foot. "Hey!!" Blue begins to poke you, inspecting your little body. You start laughing. "N-no! Stop! I-I'm ticklish!" You continue to laugh. She stops and stares at you.
"How peculiar.." she mutters. "You're so small.."
"I'm 6! Of course I'm small!" You try to make her put you down.
"And feisty. You're full of energy, like Pink.."
"Pink?" You stop and look at her. "Can you put me down? I'm feeling dizzy." Blue puts you down on the ground and you stare up at her. You look at Pearl. "Sorry for attacking you.. you scared me.."
"T-that's okay.."

You've spent weeks with Blue and Pearl, telling them the stories you made up and tell them about your mum. Eventually, Pearl stopped coming. You asked why, but Blue just said she didn't want to come anymore. You shrug it off and keep telling her stories. "Then i came out crying and screaming! And, as if she saw into the future, my mum knew i was going to be the strongest, bravest, most outrageous little girl in the universe! She held me in her arms and kissed my head and said, "you are perfect, my darling."" Blue smiles, just watching you.
"And that's how you came into existence?" You nod, sitting down.
"It's what my mum told me, anyway." You look at your hands. "I think she'd wanna meet you. You're really pretty and nice." Blue smiles.
"I've got a better idea, (y/n)." You look up at her with your (e/c) eyes, tilting your head.
"You do?" She nods.
"You come home with me. I'll be your new "mum" and take care of you." You frown, furrowing your eyebrows.
"B-but.. i like my mum.. i like it here.." Blue frowns.
"It wasn't a suggestion.. you're coming with me.." She reaches for you, but you throw a rock into her eye and run back down the hill.
"Mum!!" you scream. You trip and tumble down the hill, getting scratches and bruises. When you get to the bottom, you get up and start running again. "Mum!!"
"(Y/n), get back here!!" You run into your house and pull on your mum's leg.
"Mum!! I giant blue lady is after me and she wants to take me to space!!"
"That sounds scary," she says, smiling down at you. She thinks it's another one of your stories.
"Mum, I'm serious!! There's a lady coming after me and i'm scared!!" Your mum feels the ground shaking. "It's her!! She's coming!!" She picks you up and runs over to her shotgun, loading it. She takes you to a corner of the room.
"Hide in the safe room under here." She opens the floor, setting you down. "You'll be safe and she can't hurt you."
"What about you?! I'm not leaving you!!"
"(Y/n), get in the safe room!!"
"No!!" Blue opens the roof of your house. You mum stares and drops the shotgun.
"So you're the one who's keeping (y/n) from coming home with me," Blue says. "I'll crush you like the insect you are."
"(Y/n), get in!!" your mum screams a you.
"No!!" you scream back. You push her into the trap door and she breaks her arm after landing.
"(Y/n), get down here!!"
"No!!" You shut the door and lock it. You snatch up the shotgun and try to figure out how it works and how to hold it in your tiny arms. Blue grabs you and you start shaking. You aim the shotgun at her and pull the trigger. Nothing happens. The safety is still on. You try to figure out where it is and how to turn it off. Blue pulls it out of your hands.
"Now, now~ we don't want you getting hurt~" You whimper and continue to shake, trying to get out of her tight grasp. She smiles and heads back to her ship. Once you're on her ship, you see the pale blue shards on the floor.
"I-i-is that P-P-Pearl?"
"Yes, it is~ don't worry about her, though. Or your mother.

I'll take care of you now~"
