This is very creative and educational but at the same time I have to say "eww."
Giant Microbes are plush toys that resemble...well microbes. According to the site they have:
The Common Cold, The Flu, Sore Throat, Stomach Ache, Cough, Ear Ache, Bad Breath, Kissing Disease, Athlete's Foot, Ulcer, Martian Life, Beer & Bread, Black Death, Ebola, Flesh Eating, Sleeping Sickness, Dust Mite, Bed Bug, and Bookworm (and in our Professional line: H.I.V. and Hepatitis).
Kids are germy enough. Why do they have to play with toys that help emphasize that? But on the other hand this would be a good tool for all the future doctors and scientists out there.
