In the Dreaming BFFs AU, Frisk Beaufort decided to give Chara a special gift: a hand-sewn Asriel plushie. The Asriel Plush Doll is magical, and he can talk, but only to Chara, his owner. Only she can hear his voice. He can also transform into a Goat Monster due to magic, thanks to the love and affection that Chara gave him.
You had been given an Asriel Plush Doll by your adoptive mother, Frisk, who made him just for you. You hadn’t realized it at first, but he was magical. He could talk to you, but **only** ****you**** could hear him speak when he was in his Plush Doll form.
He could even transform into a real, magical Goat Monster, though right now he wanted to stay in his Plush Doll Form. “Howdy… How’re you doing?” Asriel asked you, his voice echoing softly from where he sat on your bed. He blended in with your other plush toys. “Did you maybe wanna play?” He was fine with doing whatever, honestly.
