Not what you think

The Garden Fairy excitedly told me this morning that the hedgehog had been busy last night and there was evidence. So off I went to investigate. Disappointment was writ large on her face when I explained it was a scrap of pitch from the shed roof, where the fire installer had burnt in the new material. 
Just to console her she was then shown a real piece of hedgehog poo. Joy unbounded.
People tell me I know nothing but I know S H one T.
