Got me - not the type to do April Fools jokes so hardly ever see them coming. Considering the reports of full adult Polar-bear/Grizzly hibrids with variations in colouration - about anything is possible.

Although Fort MacMuddy is a long way from the Arctic, it is not impossible for a hibrid to have wondered down there, so the story is plausible - all the easier to 'entrap' someone - especially me - HA!
