The Mogura Ninja are an anthropomorphic Ninja clan from Usagi Yojimbo comics. They appear in The Real World, Part 1, ambushing Noriyuki, Tomoe Ame, and Leonardo in an attempt to kidnap Noriyuki. They end up burying Tomoe underground, and have Leonardo and Noriyuki cornered, but are fought off by Miyamoto Usagi and Murakami Gennosuke. They later ambush Genosuke and Noriyuki at their campsite and take them to Hebi.
They are credited as being voiced by Eric Stuart ("Mogura Leader") and Gary Littman ("Mogura Ninja") in the casting sheets, but none of the ninja speak or make any sounds other than generic animalistic grunts that are unlikely provided by actors.
- Mogura (土竜) is Japanese for mole.
