I have no genuine reason to believe that this hedgehog is the same Scratchy as used to visit my garden in 2009, but it's certainly a hog with an itch to scratch. I don't know if a hedgehog that had fleas last year would still have them the next year after emerging from hibernation. Certainly on cats, fleas seem to be a seasonal affliction.
My belief is that "Scratchy" here (whether it's the original Scratchy or not) is a distinct third individual to visit the garden and not one of the same two hogs that have been visiting since early last month. It certainly isn't Blondie, that's for sure.
The video is at double-speed, except for the very final sequence.
