Ninjas are shadowy figures that dispense death from the dark corners of the room (I'm thinking of you, Ninja Assassin) ... unless they are these weak ninja figures as outlined by Topless Robot blog. To wit:
Ninja Stretch Armstrong
Originally introduced in the 1970s, Stretch Armstrong is one of those toys that refuse to erase itself from pop culture's consciousness. Essentially a bag of corn syrup, Cap Toys dressed him up in different guises to make you forget that his shtick can get kind of old quick. "Ninja" Stretch can't hold his weapons (he ain't got no fingers!) but at least that mask covers up that unsettling death mask grin he's got going on...
