This is Stuffy.
Santa left Stuffy peeking out of Abby's little stocking.
Stuffy is frequently the reason for a desperate, whimpering search for a great hiding place. We often find Stuffy behind pillows or under coats that have been left on the couch. One time, Abby even tried to dig a hole in the tree skirt to bury her. If one of us hears poor Abby whimpering, we don't worry that something is actually wrong with her; instead we ask whoever is closest to her whether she has her Stuffy, and the answer is consistently, "yes."
Best toy ever, apparently...
