The Mogura ninja (土竜忍者) are a ninja clan composed of anthropomorphic moles. They are the least seen of the three ninja clans, having been seen less than ten times.
As moles, their particular talents are digging and lying in wait underground. They characteristically attack an enemy building by tunneling underneath and bypassing the outer defenses; they can also lie underground until an enemy passes overhead, and then spring an ambush.
In combat, they use their long, sharp claws as weapons as well as digging tools.
Although they are formidable fighters in their element, they have weaknesses that an opponent can exploit, such as vulnerability to bright light.
