Ever see a Puff Adder? Well, here you go!
I was not messing with him when he did this, just watching him. He didn't like me that close and wellll.... He was "fed up".
(NOTE! No snakes were harmed in the making of these films! He was actually saved from the chickens, dogs, and the lawn mower, unfortunately he lost his dinner. No worries because there are millions more in the yard right now! He's safe in the bushes. Adders are non-venimous, only eat toads, and can't bite, their fangs are way far back in their throats for popping toads.)
Snakes are out, watch it! Had a heart attack when I almost stepped on him. Had my boots on and thank heavens he wasn't a rattler!
