Rocky

The Rocky (ロッキー) is a creature that appears in the Sonic X anime series and its comic series published by Archie Comics which first debuted in "Defective Detectives". They are a race of non-anthropomorphic walruses native to Sonic the Hedgehog's world.

Anatomy
The general Rocky is a diminutive form of walrus, although it resembles more a pinniped. They have grey-whitish skin/fur with a rotund head, two large blue eyes, small triangular flippers, and a fin-like hind flipper. They possess no tusks, but instead have a fussy white muzzle reminiscing a mustache and a small black nose.

Characteristics
Although recognized as animal life, the Rockies 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 Rockies and other creatures got sent to Earth, raising worries about whether they would be able to coexist with humanity. Eventually though, they got sent back to their home world. However, it was not long before Dr. Eggman returned to threaten the Rockies with his plans to take over their world.

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