Could a hedgehog do this?

I know we have hedgehogs in the garden from tell-tale signs. The other morning I noticed that something had moved some bricks that were lodged under a paving slab. These bricks have been in place for a couple of years and are quite heavy. Although they were loosely placed under the slab they were fitted tightly together (see remaining undisturbed bricks) and I was surprised that something could have moved them.

The garden is enclosed by a fence and a wall and if the gate is closed can only be accessed by climbing or by squeezing through small (hedgehog size) gaps.

So my question is, could a hedgehog have done this; or has anybody an alternative suggestion?

 

Nature prevails but why make it difficult for her.
