Hasbro applies for EU Trademark for Vac Man who apparently was A Thing VACMAN 

I'm A Ninja. You know, Ninja Stars, Ninja Nunchucks, all that sort of good stuff. I'm dispensing truth and justice Ninja Style.....in a very civilised and non-litigious kind of way. Unless you make the Ninja angry, then KARATE-CHOP! Fine, fine. I'm not a Ninja. I'm Brian Conroy, Trademark Agent and Solicitor in Dublin Ireland. Find me (in non Ninja form) at www.brianconroy.com
