Yolkians

The Yolkians are the antagonists in the 2001 film Jimmy Neutron: Boy Genius. They are aliens that represent raw eggs. They are a green goo inside a glass egg-shaped encasing with gold on the base, and talk through a speaker on the front of the encasing. They worship the god Poultra, a large three eyed chicken with super stubby wings, that hatches from a giant egg when summoned for human sacrifices. The Yolkians appear in one episode, The Egg-pire Strikes Back. They are led by King Goobot.
