I just joined yesterday. I have 12 microbes. Dust mite, cough, ebola, mad cow, plaugue (i'm not sure how to spell it), flesh eating disease,(so cute with it's knife and fork), sleeping sickness, ear ache, cold, stomach ache, sore throat, and ulcer. I love them so so much! Actually, on March 21, we had a party 'cause it was my microbes birthday.
