Playing as humans, hard, 99 stars. Find some Threshers nearby, explain to him about climate zones and the usefulness of... ahh... free labor to work the oceans. Mention Phidi and Threshers as liking the ocean the most.
Fighting the Gremak, he asks about how much of a pain it would be to 'swap out' the Threshers for Phidi if I find them, due to being clearly better.
Just so happen to encounter the Phidi. Hadn't explained they look like Seahorses...
The discussion resulted in the following tongue twister:
See sea-slave seahorses surely slave by the sea shore.
