Jungle Moon Inhabitants
The "Arthropod Alien" is a species resembling a horned arthropod which inhabits the Jungle Moon.
They are dark-blue colored and have 4 eyes. A large horn extends upwards from the end of their beak-like snout, somewhat like a rhinoceros. When decapitated, they can sprout a new set of soft unarmored limbs from their head to escape.
The "Blob Alien", nicknamed "Bird Blob" by Stevonnie, are blob-like aliens that inhabit the Jungle Moon.
They have a turquoise blue colored, blob-like body, pink or yellowish beaks, and have a single pair of limbs with curved claws. Some are extremely small, while others are much larger than Stevonnie. They are able to roll into a ball shape in order to travel on land. The larger ones are also able to fly by opening their body up into a cup shape, and closing to pump out air and rise.
The "Ungulate Alien" is a species which somewhat resembles Earth's ungulates that inhabits the Jungle Moon.
They have a turquoise blue color with pale yellow stripes, a tall hump on their back, a pinkish beak, and cloven hooves resembling those of an even-toed ungulate. They are able to shoot water out from the sides of their beak.
