Nnnn, grr nm ugh gr. Grrrrrr!, uh mmm ugh grrr. Ugh?
I'm sure daleks could go up stairs.. Did they not just kind of float up them? Or was that the way the doctor got away all the time. "I know, let's not blow these daleks up. Lets go up here instead."
If not, then I bet there were a few 'dodgy' scenes in Dr Who where daleks were somewhere other than the ground floor of a building. *
