Remember, we have earlier told you about your personal desktop missile launcher to keep those creepy colleagues out-of-your-way! Now, how about increasing your defences with your own mini army to counter any uninvited attack with Ninja Attack. The Ninja Attack warrior deployment device launches little martial arts gurus through the air and into battle. All you have to do is to simply drop by the victim’s desk and launch an attack! And, this Harmless fun will cost you a petty £4.95.
