Query: disappointed

Our 4 year old loves R. Scarry - Lowley the worm one of our favorites. We were extraordinarily disappointed with "A Day at the Police Station". An infant lost from the mom, a ghost in the bathroom (great help for potty training) I mean come on. Weak effort, not thought out - too bad. 3/4 of the book is great but that 1/4 just overwhelming.
