What editing software does Cobbler use to make his videos?

I'm having a hard time articulating this. The best way I can put it is: What software does he use to manipulate and move images around on the screen? Like getting the Cobbler characters to blink, emote, move, etc? My guess is an incredible amount of Photoshop, then basically doing stop-motion with them in his video editing software? Any help would be appreciated.
