This is our second purchase of these toys. We got the Squid Sub first and it has seen hours of play both in the tub and out. Our 5-yr-old saw the paperwork showing how other sets can be interchangeable with that and asked for more, so he got the Shark Ship for Christmas and LOVES IT! It was easy to order, came in plenty of time before Christmas and it doesn't require adult help for him to play with it, although he likes us to play with him.
I could not find this item in the store so I searched online the price was comparable to the store sales price, delivery was fast. My grandson asked Santa for this toy only so Mattel Online saved the day..No Disappointed children.
While we haven't opened this yet, since it is a Christmas present, I did take a good look at it before wrapping it and it looks to be a sturdily made toy with plenty of interactive features for our 4-year-old.
