Normal??

In that case, if there are subtle stripes that don't show up, maybe a chorus frog? Or a gray-brown cricket frog.

This is a green frog (Rana clamitans). They are often confused for bullfrogs but this one has a dorsalateral ridge. The big concern here is I think this frog is having hypocalcemia (low calcium). The frogs that I see do this almost always have hind leg weakness and then progressively become more lethargic and then develop front leg weakness and jaw weakness.

A few follow up questions for the OP:
They almost always die when it gets to this point. Has this frog been having spasms or shaking? This is another tell-tale sign.
How long ago has this guy metamorphosized?
