This is my attempt at designing a planet.
Unlike some other alien worlds, Fentil is a moon, orbiting a large, rocky planet called Olympus,.
Fentil itself is bigger than Earth, and has a higher gravity of about 1.3g and has a thicker atmosphere than that of Earth.

Like all alien worlds, Fentil's life is unique and strange.
Fentil also has organic anomalies such as hopping plants, inflatable predators and a living o-zone.
