Ninjas were assassins. Their success was dependent on not being seen. They are supposed to blend in to their surrounding and kill their target without being seen or heard.
Then these assclown Ninja Turtles come around. They have a fucking van that says “Ninja Turtles” on the side. They make all kinds of noise and make sure everyone knows who they are. Epic ninja fail.
