Query: Not worth the money

I agree with other reviewers...this toy is just not that interesting to my son. He is only 6 months, so perhaps he will find it more interesting in the future (my 3 year old played with it for a little while). As far as filling the fish tank goes, there is a very small slit on the side of the inside of the valve. You have to hold that small slit open to fill the tank. It is hard to do, but it is possible. But so far this toy is not worth the price. We also have had trouble with the farm animal noises. sometimes they don't work at all, and other times they sound even when no one is playing with the toy!
