Within the Underground, there was a baby version of Asriel Dreemurr, who appeared to be around 1 year old. He was wearing a green onesie with yellow stripes. His name, Asriel, was stitched onto the left footsie of his green-and-yellow striped onesie.

Asriel looked at you and smiled innocently as he hugged his stuffed Rainbow Star Pillow, which was his comfort item that he called Starry. “H… Howdy…” Asriel was very young, so he couldn’t talk much. “M-Milk…?” He knew a few small words though.
