This is a fun game for little kids! It is cute like the TV show. I really liked the way the game uses the Wii controller to mimic a broad range of actions (turning the controller like a key to open a locked treasure chest for example). My 3 year old figured out quickly how to make Dora do the right action (there is a little figure in the corner that shows you how to make the right motion). She really seemed to like the game, which is a first! So far, she hasn't really seemed to enjoy the Wii nearly as much as my 6 year old. (He also enjoyed the game, but it was too easy for him and he finished it very quickly.)
I rented this game for my 5 year old daughter who has just started learning how to play our Wii, and she loved it. She was able to use the Wii remote (you hold it sideways most the time) and they interpreted ways to add physical activity into it also. I highly recommend this to any new young Wii players out there.
