Yes I'm making a WIP UnderTale AU fight me ok let's go

So info on the AU will be posted later but this is just a scene for whatever it might end up not fitting into the AU at all but who cares lets go

A pale golden light filled a room, where a young goat-like monster was doodling on a crumpled piece of paper he'd discovered under his bed. His comfy sheets were pulled up over his knees and into his chest, tugged over the end of the bed to reveal some of the mattress. His adoptive sister was cuddling with one of the huge stuffed animals beside her bed.

"Hey, hey! Look! Do you like my drawing? It's of those yellow flowers daddy has!" Asriel announced happily, turning to proudly show his picture to her. She turned, peering over the stuffed bear's head and smiling.

"Looks great!" she hugged the best tighter. She's the best sister EVER! Asriel happily thought, throwing his blanket aside to scurry out of the room quickly. His adoptive sister soon ran after him. The two raced down the hallway, towards the main room where their mother was sitting.

As the two tumbled into the room, Toriel looked up from her book, smiling. "My children, what may I help you with?" Asriel left his sister at the hallway door, running up to her. He immediately waved his drawing in her face with a proud smile.

"It's very lovely, my child." she gently ruffled the tuft of fluff on his head. He giggled, his sister having returned to their room. Asriel looked at the book Toriel was reading, trying to figure out what it was. More uses for snails.

"Where's daddy? I wanna show him my drawing!" he smiled a toothy and happy grin. Toriel smiled back, though her's was softer, and gently shook her head.

"No, my child. Your father is out in the garden, in afraid you'll have to show him later." Asriel seemed upset for a moment, but then ran off again, carrying his drawing with him. Toriel chuckled softly, going back to her book.

Asriel quickly ran down the hallway to his room, shuffling through the different segments of his and his sibling's desk. He finally found an old packet of tape which he'd found laying in the garden and kept. His adopted sister watched as he stood up on the tips of his paws, reaching up and taping his drawing to the wall. Once he was happy with it he stepped back, observing it proudly.

"It looks good." He turned his head, seeing his sister smiling kindly while hugging the bear again. Asriel smirked, tilting his head up and jumping onto his bed, standing on it. His adoptive sister giggled slightly, the young goat-monster jumping a few times before flopping down onto the mattress. He snickered.
