John called it.
Upon further research, and the froglets developing quickly, I have a batch of Blanchard's Cricket Frogs, Acris crepitans blanchardi...
We tend to get the rather boring, uniform brown color scheme around here.
I don't know how I feel about this yet.
On the other hand, being extremely new to this whole frog and toad thing, perhaps these little buggers will be good training species for me...
