Surprise Visitor

Having pretty much sorted out the front of the house today I started clearing out the border in the back garden.
While removing a load of old leaves from round the bottom of some of the plants this little fella jumped out.
I think I was more surprised than he was.
No idea how he got there though. My back garden has the house on one side, a brick wall along two sides and a 6ft high fence between me and the neighbours.
This little frog must have an impressive jump.
