-I have seen borg use Dwaine to make dating simulator game with anime picture print from printer that was very amazing thing to see talent player do that.
-Bad Apple mechcomp obviously cool gimmick.
-AI core which has leg and can walk around.
-pug critter being a mail carrier.
-Gun merchant in zombie round.
