I think that you all are right! And yep, as I mentioned in the first post, these are two different frogs.

I looked up "Green Frog" and "Wood Frog" in the "Peterson Field Guides Reptiles and Amphibians" book and the descriptions seem almost perfect to me. I think that the wood frog must have been a juvenile or something, because even though the markings match, that guy was TINY (literally the size of a penny). Thanks all!!
