A Ninjohn is an enemy that appears in Super Paper Mario.
Ninjohns are ninjas that are only seen in Sammer's Kingdom where they sometimes appear during fights. Ninjohns are stronger than Ninjoes and are green in color. Like with Ninjoes, Ninjohns attack by throwing ninja stars around. They are also very fast and can prove a nuisance when dealing with the Sammer Guys. Taking out the Ninjohn first is the best strategy.
