We received Ocean Treasures over the weekend and played with it briefly between beach and other outdoor activities. My 4-year old woke me up at 5:30am Monday morning asking if we can play with it again. Her and I did some of the activities, plus made an egg carton pirate ship to go with it, for almost 3 hours! She was so engaged and enjoyed it thoroughly. The bunny box was great too, but this one is really phenomenal. It is items that I wouldn't have thought to buy and is really different for her to play with. I expect we will enjoy this for many more days, weeks, etc.
