Need help ID this frog before it dies

[Cesiumsponge]

I know nothing about amphibians. However I ordered a tropical potted plant from Florida, and when it arrived up here in Washington, I opened the package and a frog jumped out of the soil! I have no idea what type it is or how to care for it. I don't wish to simply "get rid of it", so any help will be greatly appreciated. I've attached pictures in hopes someone can help.

I would like information on what the bugger is, and some care tips such as food/water/houseing etc so that I may keep it alive long enough to find someone who would be more qualified than I. Hopefully I can get a positive ID and some tips because right now I have it in an old cookie jar (with air holes) and some dampened moss and I don't know how long it will stay alive this way. The frog will easily fit on a quarter.
