I give him more lore (TW, Gore in the desc)

He was a doll lying flat on the cadin and was 1.5x the size of a hand, when nick found him, he did a ritual to make him come back to life by putting a dead fox near him and putting the fox's flesh inside of him, føx doll went to life, and he has been Nick's friend since.

He shares a hive mind with nick, if nick is hurt, Føx doll also feels it.

The horror form is basically that his crystal like blub from his head (from tails doll) was broken, blood spilled from his stitches and his pupils dilated, his body rotted and darkened (because it acts as his life support, without it, he will rot.)

Nick is from u/dearfuse and Føx doll is by me
