New update
Piggy Mail, Legendary Hat (Tribal Mask)... but how about bug fixes?
Edit: Feats reset?! Gotta claim them again before it gets fixed?
2nd edit: There are apples in treasures, too. They don't seem to replace what's in the box, but are additional to them. It looks like randomly 1 in the box, 1 to x times per day depending your (or your hatchlings?) level. Helps to have the little bugger fed.
