Right in the middle of whatever Spider is doing-brushing his teeth, reading a book, or watching a storm-he thinks of Frog. The strange thing is, Frog isn't even nice. On the contrary, she's quite rude. She never suggests going for a walk, never cares if anyone is hot or cold, and, most of all, she always says NO. And there are all kinds of NOs: the big NO, the small NO, the baffling NO, the mysterious NO, and sometimes even the repeated NO, NO, NO. Spider keeps all these NOs tangled in his web, but when a storm sweeps everything away, it brings a new friend who helps him discover the value of YES.
