The Cuckies resemble white-feathered chickens with a round-shaped head, two large greyish blue eyes, a tiny orange beak, and thick cheeks. Their wings are medium-sized compared to their body, which is at the same size as their head, and they possess smooth tail feathers and soft orange feet with three toes on each foot. Additional features include a rather large red comb and a red wattle under their beak.
Although recognized as animal life, the Cuckies are remarkably intelligent and sociable, having been shown to live in civilized environments.
At some point, Cuckies began showing up on Earth, presumably due to the Chaos Control irregularities occurring after the Space Colony ARK incident. Despite concerns that their cultures would cause tensions, the Cuckies maintained a peaceful existence alongside the humans until they got sent back to their home planet with the other creatures. However, Dr. Eggman soon returned to threaten the Cuckies with his plans to take over their world.
