"Oh, so the seahorses were aquatic - I got them after the butterflies learned to make glass, I put a fishbowl sort of thing over my avatar's head and carried ballast and it could get around okay underwater, and I found seahorses living in a coral reef, and they had these pests - little jellyfish things, swarms of them, not intelligent at all, I tried to see if maybe they were but they weren't, and they were like mosquitoes to the seahorses. And I tested a bunch of different stuff to see if I could repel them, and I tried finding where they laid their egg packets, and finally I just made a big net and put it around the reef like a fence - with gates in it. And I was in the middle of going around and killing all the jellies and eggs that were still inside the net so this could be a complete solution."
