Well, I hit a funny snag.

Today I won against Chayne and finally got to unlock the ability to find eggs in the wild.

Decided to do my first egg hunt in Low Caprice and got a Briny Bronco, a Lunatick, a Ethereal Serpent, and a Barracuda, but... two of the remaining eggs are inaccessible at the moment over they're in those little square ruins and, since I was running around there in winter, it's summer. They're stuck underwater until the season that drains the lakes arrives.

Welp, guess I gotta start hunting in the other enchelons for now until those two eggs are accessible then.
