Nice!
If you decide to take on a swimming animation, I've got a suggestion for that, too.

If this "land frog" is (example model name) c_frog1a, make a c_frog1b that is 1 line number away from the "land frog" in appearance.2da, with the swimming animations. That way, if the frog is in an area a builder marks as "water", a script can easily change the frog's appearance to the next one in the list (swimming), and if it moves out of the water area, it can change it to the previous one on the list (walking/jumping).
I like frogs, by the way. They're just cool animals.
