the lil coal smile and empty eyes with lil lights in them were his dad's idea, the lil shoes were lila's addon and so was the lil orange button nose, the gloves were kinda a team effort cuz whats a snowman without gloves?(well frosty, but u get the point)
oh, and the kinda large button on his chest? well there's actually kinda a deeper story to that.
originally, a coal button was in it's place, matching the one under it.
on skid's first christmas day, the family awoke to basically a MOUNTAIN of presents under the tree. usually there would be just a few presents- presents from the couple to each other, with a few extra from the husband's business companions, who had been basically too busy to give anything in person. but that special year, there were many more gifts- all from "santa" to skid! ..and also a few from his parents too.
...but strangely, quite a lot of the presents NOT from the parents were rather strange. they weren't toys nor decorative things, they were simply items with symbolical meanings that a child wouldnt exactly know what to do with. to this day, these items sit in a box in the attic, as lila nor skid had no idea what to do with them.
some of the ones that stayed out of the box were toys, of course, or other items that skid actually enjoyed. one of these was a large, black button- one specifically that his dad gave him, saying it was "good luck".
is it actually good luck? well nothing seems to harm skid so he would say so! that's why he replaced one of his coal buttons with it, wearing it ever since he got it!
is it magic? probably not- the only thing that happens when it's removed is skid's emotional distress.
..nowadays, he keeps it on for more than just the luck. he keeps it for the memories.
