a sort of "Shogarty Bogarty" type of creature ?... ( if I did in fact hear that term somewhere and not imagine it ?)
I think I know what you refer to Richard. I think you are thinking of Bobbetty-Shooty which is not the name of the Devil but a name for Hell. It occurs in what many consider the very best of the old Punch Scripts. It is the one by Robert Brough in 1854. It is reproduced as an appendix in George Speaight's "Punch and Judy, a history".
George Speaight and rival historian Michael Byrom differed on many aspects of Punch but they did agree that this was the very best Punch script.
Here is the snippet I am guessing you are recalling RIchard:

[A horrrid, dreadful personage rises behind Punch, and taps him on the shoulder]
"You're come for."
PUNCH (alarmed) Who are you?
THE HORRID, DREADFUL PERSONAGE (in a terrible voice) "Bogy!"
PUNCH "Oh dear, what do you want?"
BOGY. "To carry you off to the land of Bobbetty-Shooty, where you will be condemned to the punishment of shaving the monkeys."
There is at least one of the regular performers at the May Fayre who do use "the land of Bobbetty-Shooty and shaving the monkeys" in their script. So if you haven't actually read this script Richard, you may well have heard this bit of it.
As for the "shaggy fur type of body" - well I've certainly seen that somewhere. I think I recall a photograph of a German marionette devil from a Faust play, which was dressed in black shaggy fur. The trouble is that modern kids don't really recognise the Devil as a character even in stereotypical form and if you gave him fur you'd really confuse the little dears. Mine has fangs (its based on Peter Frazer's lovely drawing) and the kids think it is a Vampire.
