Shape-shifter

What did you think this was when you first glimpsed it?
This is on the beach at Badnaban Bay - from a distance I thought it was a dead deer or animal of some sort and it wasn't until I came closer I saw it was a tree stump. Then when I walked around it it looked like a dog lying on its side!
Anyhow I thought it made a good blip for today.
Back to Thurso tomorrow :(
