As much as my nine-month old enjoys this toy, I have put it away for good this morning. It is unsafe and is engineered quite poorly. One of the screws would not fit when putting it together, so we had to go to the hardware store to get another one. The sound also worked for less than a week. What is more disconcerting, however, is that like the other children in the reviews, my son constantly pulls this tunnel over on himself while pulling up. He has suffered many bangs and knocks since Christmas because of this toy. Shame on Fisher Price for creating such a poorly designed toy. DO NOT PURCHASE!
