Teddy Bear

[Kilroy]

Didn't Desmond pack a teddy bear when he ran off? Maybe the "Others" scalped him and took the bear. Or maybe the Teddy Bear is a "Favor" that all experimental subjects are given.

If all those bear footed others are kids. Maybe they are escapees from the Pirate Other's experiments. That could be why the Pirate others want Walt and Alex and Claire's kid.

It's one of the kid's bears the others took a while back in The Other 48 Days. The little boy who saw his sister being revived.
