Step 1:
SCAN OUTER SURFACE
Look all around the outer layer of vegetation.
If you do not see the frog where you think you should, start exploring
one layer deeper into the brush.
If branches are in the way of your vision, get the clipper and snip
them away carefully.
Moving slowly and not with any sudden motions, drop the frogless branches
away behind you.
Wait for the next call before continuing.
The frog is probably within inches of your face by now, and you suddenly
spot it.
