I had a kids folk song CD some years back with several fairly common folk songs, like John Henry and other things. But it had one folk song I haven't been able to find anywhere. The lyrics went:

Some frogs jump one foot, two foot, some frogs jump four
My frog jumps fifteen miles and then jumps some more

If I recall correctly, that was basically the whole songs for around 2 or 3 minutes. Any help identifying it would be appreciated.
