The partial note can be found by inserting 100 numulites into one of the stone chests inside the House on the Hill on Fossil Island. There is a chance nothing will happen or a spike shooting out and stabbing the player for 9 damage, wasting the numulites.
This note can be added into the Fossil island note book.
I have witnessed this first hand. The young are deliberately left beneath colonies of the spore until they pass out, choking. A violent affair, but one I have grown to understand is necessary. Perhaps my own concern of the treatment of subject 1 were invalid. Pain has its place in the needs for advancement.
