Vicious Self-Sufficiency

Two years since he arrived at the Secondary Landmass, Krune arrived at the bottom of the rock pillar, reaching the ground. Creating a hole for his exit, he peeked out, taking a look at his surroundings. 

What he saw through his sight and his Sonic Radar startled him. There was only one monster species in the place, which seemed to go through two stages of life: the pupa and the adult stage. 

An adult laid down eggs at the banks of the river. Upon hatching, the hatchling entered the river water, feeding on the tiny organisms living within the pores of the coral reef at the bottom. This seemed to be their prime mode of food. 

In any case, the coral reef was vast, spanning the banks of the entire river. Since the river was two kilometers wide, it was massive, stretching for the entire length of the meandering river that spanned from one end to the other of the 300-kilometer-long island.
