The Germs were 12 vinyl creatures sculpted as effigies of various diseases, though you are unlikely to find a "Winkyblinkyigoopiola", i.e. the germ that causes eyeball goo, in any medical journal.
Other disgusting specimens were the "Innyouttyitiis," a flaming red organism that was apparently responsible for belly button lint and the horn-nosed "Ahahchoosiosus," commonly known as the "sneeze."
Each germ was around 3 inches tall and had big, bulbous, crossed "cartoony" eyes. The creatures were luridly colored in a way not often seen in the 80s...in fact, they looked very much like a toy Mattel might have produced in the "psychedelic 60s" (see my article on Kiddles for more info!)
Germs came with a "lab report," a small paper pamphlet that explained the details of each pestilence in a decidedly non-professional "street slang" way, and offered such useful information as, "You can sometimes coax the little creep out by leaving some garlic bubblegum near your sneakers overnight."
Each germ was housed in a test tube. This might have been fine if you had a test tube holder to put them in but without one your only option was to turn the things over and display them upside down. You could, of course, take your germ out of its test tube and "right" it so it would display right side up in its tube but those who did were assaulted with an unpleasant rubber scent that was hard to forget. I read a vague story that the toys were considered dangerous but couldn't find out why. I suppose a child might have tried to eat the creatures, though they are certainly ugly enough to have dissuaded, I would think, all but the most daring.
In fact, The Germs were designed in such a fleshy, anatomically suggestive way that they bordered on obscene; many were the times I had a dirty-minded friend over to examine them and speculate on what they were "really" modeled after.
