There should be a theme for all pets that is based on a lunar eclipse.

You could make a theme based on lunar eclipses for one of the next fests, probably. I don't see how just up-and-rising with a new non-zone-exclusive theme for a fairly common event could be very beneficial. There is the blue supermoon eclipse coming up soon, but the winter fest is likely going to have ended by then, and making a new zone for roughly two days would be quite the unnecessary strain on Krin and co.
