We ended up perusing the Giant Microbe site, which has many more goodies than when I was last there.
When I found out there were now plush maggots available - both singly and by the petrie dish - I had the urge to buy about a hundred of them and force one of my friends to lie on the floor and be randomly covered with them. I already have several rolls of *crime scene - do not cross tape* left over from an old Archie McPhee package. We could take photos and make our own csi comics!!
