He looks fine to me also. Slightly on the heavy side, though. You may want to cut back on the feeding a bit.... but just my opinion.
Like Gary, my frogs will sometimes just 'chill,' for days sometimes. So that doesn't alarm me. And his chin being a little soggy, can you elaborate?
if it's his neck, it will look soggy or saggy after calling. If it's his lower jaw, that could be a sign of calcium deficiency.
