So when you’re getting your precious ninja rest on, it’s understandable that you would need someone (or something) to guard the
headquarters.

That’s where my main ninja Room Defender comes in. Trained in a variety of martial arts, dance techniques and broadway show tunes, Room Defender is a snazzy little killing machine with soul.

In the $45 dollar version though, the features are fairly limited.AA You forfeit the heatseeking missiles and the full anti-aircraft arsenal for something far more important: a compact carry-on size.AA The Room Defender, armed with a motion sensor and projectile foam discs, will attack any intruder into your space.
"Just place this little guy toward the door, watch & wait.AA Once someone comes within a few feet, the room defendera€™s motion sensors react with a salvo of 16 foam disks hurled at the intruder."
