Morbo's species

Morbo's species are a sapient race of green-skinned belligerent bipeds, which might be planning a large-scale invasion of Earth.

Biology
Members of this species are hairless reptilian humanoids with large pulsating heads bearing clearly-visible veins. They have green skin, purplish lips, and bulging yellow eyes with vertical slit pupils. Their ears are round, and they also have a couple of small nostrils. Their hands are tridactyl, without any visible claws or nails, although they do have sharp teeth suggesting that they might have evolved as predators.
