Haunched
It is dark, prime time for feeding and I am nocturnal and I am hungry.
I sit crouched on this barren slab, motionless so my position is not discovered until it's to late. The slight wind might carry my sent, but that's a chance we all allways take.
My form is haunched, belly barely scraping ground, my powerful back legs ready to propell me at lightening speed in any direction my agile body needs to go. There is a light rain starting to come down, I love it as it will help to dampen my scent and any sound that could give me away.
The anticipation kills me just sitting here waiting, all stealth-like. The rain might also be a deterant for my prey, but wait, there in the cloudy mist I can see a shape, it is hurtling right at me, oblivious of my presence?
Nope, damn Hawk tried to eat me but this frog just hopped away.
