Picky (IDW)

The Picky is a creature that appears in the Sonic the Hedgehog comic series published by IDW Publishing. They are a race of small pig animals that live on Sonic's world. The Pickies are constantly captured by the Eggman Empire, who uses them as batteries for their various Badniks.

Anatomy
The general Picky resembles a rotund domestic pig slightly less than half a meter tall. However, they are remarkably humanoid in anatomy, even standing on two legs. They have light pink skin and possess large round heads with two large black eyes, triangular ears, and small stubby snouts. Other features include relatively small torsos, thin and short arms with fingers, stubby legs with long feet and two cloven for toes, and a short coiled tail each.

Imprisonment and freedom
Following the emergence of Dr. Eggman, the Pickies have perpetually been kidnapped by the Eggman Empire to be used as power sources for the Badniks employed by the Eggman Empire's associates. Over the course of time, Sonic the Hedgehog and other parties have freed countless Pickies from their robot shells during their battles with Badniks.
