Ricky (IDW)

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

Anatomy
The general Ricky resembles a brown-furred and round-shaped tree squirrel, although their anatomy is slightly humanoid. They have large heads with a small torso, arms with four-fingered hands, thick yet stubby legs with long feet and three toes each, a long and curled bushy tail each, two large black eyes, and round ears on top of their heads. Additionally, they have peach fur around their faces and on their bellies. Other features include cheek tuffs, medium-long brown/pink noses, and hair bangs on their foreheads.

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