OOo, sorry to rain on your parade with the cute frog, but that one in Hetty's picture is an invasive Cuban Tree Frog. You can tell by the round toe pads on their fingers and toes.
Here's a good link.

I'm here to confess to being a mass murderer of these guys. They eat everything, including the native tree frogs and toads! They even eat the goldfish in my pond! They also have poisonous stuff in glands on the backs of their necks that can make a cat or dog very sick if they pick one up in their mouths.
