Meet Rebecca . . . she spends a lot of time at the doctor’s office. She has lots of overprotective grown-ups making her take medicine, and when they fight (as grown-ups always do) it doesn’t make things any easier. That is, until this guy comes along:

Meet Ernest . . . if he looks silly, that’s because he’s a germ, one of the “good germs” that Rebecca’s doctor says will help her get better. But Ernest is more than that; he’s Rebecca’s best friend and partner in crime . . . er, we meant partner in adventure!

Together, these two are unstoppable, especially in a snowball fight!
