Kri-krill

These small, bat-like animals act pretty much like pigeons for Grimlahd. Flocking to heavily crowded areas, the creatures feed off the refuse left behind by civilization, but can also make wonderful pets for misguided children. Roughly a foot in length, from head to tail, they are typically dark gray and look like flying iguanas. Leathery wings expand two feet to either side, and allow the kri-krill to glide more than fly. The creatures perch, often upside down, much like bats.
