Ninja constrictors are invisible ninjas that respond to thoughts and do only one person's bidding. Every time you kill one 2.35 appear in it's place. They are all around all the time, but they always spring behind you when you look for them.
Be careful what you think when you are around them, because they might respond even if you don't want them to.
*thought* Fuck Conan O'Brien, why is he so tall?
*Ninja Constrictors get busy ;) *
