A creature that has almost nothing to do with Gopsi, or the black poles whatsoever, but I think they're cute, and worth putting into a book, especially if you want to acquire an Aardvark Bath. In fact, the first part of that sentence is a complete load of Baboon's urine, as the aardvark is very relevant to Gopsi.
The word can also be pronounced "Hardvaak", but this is incorrect, and no-one in the entire existence of man kind has anyone referred to an aardvark as a "hardvaak". This pronunciation is used only by small anthraxopods, on a planet somewhere near Alpha Centauri.
