Educational Innovations has added a bunch more plush microorganisms to their roster: brain cell, chicken pox, fat cell, maggot (not, strictly, a microorganism), MRSA (complete with a cape as befits a super-staph), penicillin, staph, T4 bacteriophage virus, toxic mold, chlamydia and herpes. Giving someone a deadly disease was never so cute! (The grad students in my group got a bunch of these things a while back, so I bought a plush white blood cell to keep 'em in line.)
