Castaway's Journal Day 2

As I explored around on foot, I found a sphere that emits a peculiar blue light.
I threw it without much thought, and the creature it landed near transformed into what seemed to be light, as though the sphere had absorbed it.
Unbelievably, when I tried throwing the same sphere again, the creature reappeared from the light and stared at me with what seemed like an amicable expression.
As I began to create a shelter to protect me from the elements, the creature astonishingly began to help me.
How useful. Wanting to deepen my connection with this living thing, I decided to name its kind |Pals|.
To match, I christened this land Palpagos Island.
