Mogura ninja

The Mogura ninja are a ninja clan in the Usagi Yojimbo story world, 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 by bright light.

The Mogura appeared in the 2003 Teenage Mutant Ninja Turtles episode "The Real World, Part I," where they attacked Leonardo, Tomoe Ame, and Lord Noriyuki. Though they were driven off by the timely arrival of Usagi and Gennosuke, they were successful in kidnapping Tomoe, taking her to Lord Hebi.
