This game is unfortunately very bad for the DS. If they had just done a straight port, then it wouldn't be a problem, but they tried to add too much stuff. They made it a requirement that you upgrade your vehicle, but they don't tell you what each upgrade does until you buy it and it is a bitch to get money to buy them. Also, to get boost, you have to use the touch screen and for the Hovercraft, you have to blow into the microphone. There is also a hard mini-game in which you have to go blow out torches, and unless you do it in time, the elephant won't let you change vehicles or characters! This game wants to be good, but the only good part about it are the memories you'll get by playing it for about 15 minutes.
