I thought I got a deal.

There was a yardsale down at the trailer park on Saturday. I bought a knock-off of one of those Roombas. If you don't know what they are well, they are a programmable, circular device you can program, and they automatically vacuum while your doing other important things like laying in front of the television, or drinking beer. Anyway, I set the thing for vacuuming my shag orange carpet in my 1972 single wide trailer. Everything seemed normal, so I went over to visit Lilly Ann Marklekrot, who lives a few trailers from me. We played a few games of Parcheesi, and after a few more beers, I headed back to the ranch. Much to my amazement my Chinchilla, let's just call him Chinny, was nowhere to be found. I noticed the Roomba was smoking in the corner, and one of Chinny's hind legs was sticking out from some kind of vent on the machine. It looks like it's been taken apart before, and all the screws seem stripped. I guess my question is: Should I use a Phillips or a flathead screwdriver to free Chinny?
