Ninjas are mammals. Ninjas fight ALL the time. The purpose of the ninja is to flip out and kill people. Ninjas can kill anyone they want! Ninjas cut off heads ALL the time and don't even think twice about it. These guys are so crazy and awesome that they flip out ALL the time. I heard that there was this ninja who was eating at a diner. And when some dude dropped a spoon the ninja killed the whole town. My friend Mark said that he saw a ninja totally uppercut some kid just because the kid opened a window. And that's what I call REAL Ultimate Power!!!!!!!!!!!!!!!!!! If you don't believe that ninjas have REAL Ultimate Power you better get a life right now or they will chop your head off!!! It's an easy choice, if you ask me. Ninjas are sooooooooooo sweet that I want to crap my pants. I can't believe it sometimes, but I feel it inside my heart. These guys are totally awesome and that's a fact. Ninjas are fast, smooth, cool, strong, powerful, and sweet. i copy this from that ^ webpage Have you play final fantasy 6 that nija gu kill his family for a pearl. I did not finish the game am nearly finish hahahahah!!hahahahahha
