My 2 1/2 year old LOVES sharks, but because of this bucket he became familiar with other sea life. He quickly learned about dolphins, whales, octopus, and fish. This is such a great bucket!! It has such a good variety of sea life and all made out of heavy duty materials. They're great for the tub or for outside in the pool. I was so impressed at how quickly he learned the difference between a shark and a dolphin or a shark and a whale. If your little one is interested in any kind of sea life, then this bucket is perfect. And the price just can't be beat!!
