Orenjisaurus

The Orenjisaurus was a smaller Willosaur relative. It was orange and blue. It lived on the planet Tamaran-2.

Cell stage
The Orenjisaurs fell from the sky as a tiny cell, the Orenjicell, and ate and ate. It started growing and got a horn-like appendage that let it prey on smaller cells. It grew and grew, and eventually became a large cell.

Aquatic stage
It eventually got very big, and evolved to a large mosasaur-like fish, namely the Orenjifish. It preyed on tiny fish, and grew to a large size and went on land as the fully-developed Orenjisaur.

Creature stage
It killed a smaller creature and scrapped a bit over it with a smaller creature, namely the Crockosaur. It won the fight, but shared with the Crockosaur anyway as it could not see it suffer. It then mated with a female and laid an egg, which soon hatched. The parents taught it how to hunt. It soon became a master of hunting and mated itself, and eventually the Orenjisaurs were very populous. They started storing food eventually.

Tribal stage
In the Tribal stage, the Orenjisaurs gathered a huge coconut and started living in it. It was very comfortable, and they crafted tools out of the sticks they once used for their nests. They hunted and fished with them, and they bartered with their neighbors the Crockosaurs. They became good friends. Eventually, the Orenjisaurs decided to join the Crockosaurs, and they grew so much together that their carpentry got very good and they built large buildings to live in.

Civilization
Their coconut, as they found, was not very big. So they built new ones. New ones as tall as the Empire State Building.
