A Mauzhertz (pronunciation: MOWTS-hairts, Grimm: MOWZ-hurts; Germ. Maus "mouse" + Herz "heart") is a mouse-like Wesen that are harmless and shy. They first appeared in "Of Mouse and Man".

Characteristics Edit

When they woge, they gain beady eyes, whiskers jutting out from a pointed nose, more facial hair, large ears and over sized incisors. Female Mauzhertz have an overall similar woge, but their amount of facial hair varies from none at all to almost as hairy as males, and they have less pronounced whiskers. They do not have any strength enhancement and are generally quite weak.

Behavior Edit

Mauzhertz are, by nature, very timid and exceedingly cowardly, oftentimes afraid of their own shadow. They are very predictable which makes them easy prey for Lausenschlange, their natural predators.

Mauzhertz are a friendly species, and will go out of their way to avoid trouble. Consequently Mauzhertz have never been at odds with the Grimms. Prior to Nick Burkhardt recording Martin Burgess' murder spree, it is unlikely that a Grimm had ever recorded an instance of a rogue Mauzhertz, as Nick could find no mention of them in any of his Grimm Diaries, and required Monroe's help to identify them.

Despite their passive natures, Mauzhertz can occasionally be found in the seedy parts of society. A good example of this would be Sauly, who had connections and sold tickets for Leo Taymor's Löwen Games. Likewise, Nick spotted at least one Mauzhertz in prison. ("To Protect and Serve Man")
