The Room Defender

This toy is great both for your kid and for the office. The room defender works by pointing it in a direction where you want it to auto-sense movement. The victim crosses its field of vision, the Defender fires 16 foam discs at the unsuspecting intruder.

The defender has four modes, target, ambush, warning, and assault. We'll leave you to think of what each one of those modes could mean. But your office buddy Bob knows what it means—no more swiping Skittles off your desk.
