This little guy is amazing. We bought it for our 2 year old for her birthday. It's so great. When we turned it on our 4 year old started jumping up and down saying whoa we're underwater LOL. I think we will be getting anything one soon so he can have his own. The best part of it is it's all adjustable. There are volume controls right on the shell for the sounds and a button to control the movement (on or off) and there is a switch on the bottom that you can use to adjust how BRIGHT the light is! Love it! It comes with batteries but we had to change them right away because the movement stopped working. As soon as I put new batteries it worked fine. Not really a big deal. The only draw back is the screw for the battery compartment is small. Like too small for a normal screw driver. I ended having to use a knife to unscrew it which is a little frustrating considering I feel like it's going to get a lot of use lol But it's a minor flaw for how great this turtle is.
