Camouflage

Almost perfect, would you say?!

After a long, good squint I all of a sudden saw it: it's a tree trunk snaking up into the sky! :)

Venomous head. :O

I was going to comment that it was an excellent job of a Dachshund pretending to be a tree trunk.

Took me quite a while to see the snake … Although once you know it's there, it seems to be more obvious.

That was hard to find!
