Drones~!
Marblebot; Like the name implies, these look pretty much like a shiny little marble, until they transform, and start sending messages.
He has quite a few of these, but thanks to their tiny size, they're not terribly threatening, and therefore try to keep themselves hidden as much as possible.
Laserbeak Deployer; This one is a high altitude reconnaissance Drone. It records, and re-transmits messages sent to it from the marblebots, or can be set to a singluar function like 'retrieval'.
