At first glance of this book I assumed it was going to be an entire book stroking Miss Piggy's ego, which she so often does herself. It was actually somewhat endearing. Her utter obsession with Kermit is a consistent theme throughout but it isn't annoying. It's rather cute, you can spot all sorts of little things with Kermit's face on them.
Overall it's perfect for little girls around the age of 5-8 when they are at that magical dreaming age.
