I loved the podcast ... and Hugo, I used to have one! I got it from my aunt and uncle for my 7th or 8th birthday. I think the idea was that he's a spy and you used disguises to help him to go incognito.
There were stitched up eyelids, wire rimmed glasses and weird wigs that come with him - and a pot of very nice smelling glue to stick the masks on. I remember the smell of the glue particularly. My Uncle used to work for Texas Instruments in Dallas so it's very possible he brought it home with him and it wasnt available over here. fond memories!
