Franny is a frog who gets bored sitting all day long on a log with her brother and sisters and gets fed up with being called Franny Puff because she, unfortunately, puffs up in the wrong places and at the wrong times. So she decides one day to leave them and go down to the river for a while, but when she gets back, they are very cross and warn her that there is a virus around and she must stay at home. This makes her even more determined to get away and try to find the virus, and what adventures she then has!
