That's where the idea of the critters came from.
Being old enough to remember Gremlins the first time round, we liked the idea that there were both good and malevolent creatures behind the scenes. So as you worked they're trying to pinch your bag or spill coffee on your laptop.
This enables us to subtly re-enforce our message that most of us are stranded without our stuff, without beating people around the head with it.
Over time the family of Critters will evolve and change, we're not quite sure where it will end up.
