What do Karen and Tsukihi see Ononoki as?


They told Araragi he would never grow up since he was still talking to a doll
(Ononoki) at his age in _Tsukimonogatari_ episode 4, 31 minutes in. It's
always hard to tell how different people perceive the same phenomenon in
_Monogatari_ series, which is fun and puzzling.

What do Karen and Tsukihi see Ononoki as? Do they not perceive Ononoki as a
human being?




If I recall, they won her at the Arcade, so they see her as a simple won prize
doll.
