Characteristics
Like actual animals, the Rickies speak only in a language consisting of chirps. Although recognized as animal life, they are remarkably intelligent and sociable, having been shown to live in civilized environments and reside in their own houses.

Anime
As a result of the effects of Chaos Control, several Rickies and other creatures got sent to Earth, raising tension about whether they would be able to coexist with humanity. Despite these concerns, the Rickies kept a peaceful existence on Earth, with one even playing around with humans, until they got sent back to their home planet with the other creatures. However, it was not long before Dr. Eggman returned to threaten the Rickies with his plans to take over their world.

Archie Comics
A number of virtual Rickies appeared in a simulation Dr. Eggman trapped Sonic the Hedgehog and his allies in. These Rickies would appear whenever Sonic freed them from badniks or capsule prisons.
