Exactly, everyone has their own ideas. I'm pretty sure Penny is based on Sally from The Nightmare Before Christmas. Her weapon looks like a series of needles and thread; Sally was a ragdoll and Penny may be a cyborg/android; the episode introducing Penny was released on Halloween; Sally herself is based off the Monster from Frankenstein (a classic book); and finally the person that drives away with her in the last episode says something very similar to what Sally's creator says when she escapes, something along the lines of "You aren't ready for this level of excitement."

Whether this is true or not is unknown at this time, but currently all theories are just as good as anyone else's considering we can't prove any of them until there is official confirmation.
