I'm really sorry what's happened so far, but I hope that you find her soon. Papyrus is very cute
. Was he named after the character from the game Undertale?
I suggest sprinkling some flour on the floor and near the hole. That way, if she comes out, you can see paw prints. I feel stupid for not remembering this before as normally someone mentions it.
I'm sure you'll find her soon! They have been cases on here of the hamster being missing for a month, then showing up again. I believe this happened with Nancy's Hamsters Godiva.
Hopefully, Papyrus will help lure her out.
