Traits

A lesser jaw trait where a pocket develops at the corner of the leech's mouth in the same fashion as a container mutation might, giving the leech the appearance of having cute cheeks. 

These differ from markings in that the cheek is functional and can be used by the leech to display blood, fluid, or small trinkets that it feels have value.  Incredibly docile leeches may even allow their owners to customize the cheek pockets with their own things, making this trait a popular pick for the decora and ita scenes. 

Note: It may be accompanied by any type of teeth.
