This was a gift for my nephew, & he loved the book, through an amass of presents to open he stopped went right to Dad & asked it to be read. This continued off & on throughout the day with other family member's. My Nephew has has a few issues with having to go through many Dr. visits due to a stream of allergies through his first 2 years of age & also a Severe ear infection which burst his eardrum & eventually lead to tubes with-in his ears. I believe that this has comforted him knowing that one of his cartoon heroes had to go to the Dr too!!! ~T
