A 'poof ninja' is the most extremely radical creature in all the galaxy. It can poof from one place to another and sneak up behind you. This usually leads to slicing your throat open and screaming poof!
Elissa: Dakota is a poof Ninja!
Vikki: So I've heard!
Dakota: *Poofs* *Slices Vikki's throat open* POOOOOOOOOF!!!!!
