Mauzhertz

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

Biology
Upon Woge, they gain beady eyes, whiskers jutting out from a pointed nose, more facial hair, large ears and oversized incisors. Female Mauzhertz have an overall similar woge, but don't gain extra facial hair, and have less pronounced whiskers.

Behavior
Mauzhertzen are by nature, very timid and exceedingly cowardly, oftentimes afraid of its own shadow.

Mauzhertzen are very predictable which makes them easy prey for Lausenschlange, their natural predators.

Much like their Eisbiber cousins, Mauzhertzen are a friendly species, and will go out of their way to avoid trouble. Consequently Mauzhertzen have never been at odds with the Grimms, indeed 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 Daries, and required Monroe's help to identify them.

Despite their passive natures, Mauzhertzen 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.
