[Sans is floating, absorbing the nothingness as much as he can while still lingering near Papyrus and the sun lamp. As far as Sans is concerned, Papyrus isn't supposed to have a body either, so between that and how scattered and distracted his thoughts are, he's operating on a bit of a time lag when it comes to noticing how Papyrus's arm changes. The text comes several seconds after Papyrus changes things up.]
