Mouse for Genesis is comprised of two main Full Body Morphs - the extreme "Mouse" shape and the additional additive "Dress Up Mouse." The Mouse shape is used when you want your character to truly look like an animal. The Dress Up shape is much more anthropomorphic, applying the mouse head to a re-proportioned Genesis 3D model body. It is this Dress Up shape which is recommended for mice you intend to gown in fancy attire.

Working in the background of the Mouse shape are nearly ninety JCM and MCM morphs to make the character as poseable and emotional as possible. Though even with all these elements working in the background, Mouse is an extreme shape, and will require some tweaks to pose presets from other packages (specifically in the shins).

In addition to these hidden morphs working behind the scenes, there are additional pose sliders for the ears in pose controls/head/ears. Mouse comes with one additional special full cheek expression, "mouse chow down," which is located in the pose controls/head/expressions selection. Mouse also has a weak jaw shaping dial in Shaping/Mouth/Fantasy sci-fi and ear size shapes located in Shaping/Ears/Fantasy Sci-Fi.

The character comes with an old fashioned plop-it-on-the-butt tail. This poseable smart prop is quite limber, and its location can be adjusted to ensure that it pokes out from underneath shirts and jackets as opposed to jutting through them. Mouse also comes with whiskers. Four MAT poses are included in this initial release, as well as shaggy and short haired LAMH presets.
