I think Frank's a Roomba. Who chases cats.

I am tempted to say Andy is a blender. He's been slowly seducing Brendon the toaster, showing off tricks with his cord and everything, and then Mikey came along with his fork. :( But it gives Blender!Andy an excuse to ~comfort poor Brendon. I can't decide if it's meant to be or a tragic starcrossed love due to the electrical elements / melts when too hot and also contains liquids issue.
