On top of their large bodies rests a head. This head contains most of the brain, but over thirty percent of their "grey matter" is located in their torso. Two proportionally thin arms and proportionally thick legs are attached to the torso. The legs are for supporting their heavy body, while the arms are mostly for fine manipulation of objects. Although, legs can be used if need be. However, the strength of these limbs makes it difficult to handle objects with care.
